The error you have indicates that it is unable to download the technic and minecraft files, it throws an unable to connect exception and runs out of retries. I thought it might me a problem with your java but it could also be a firewall or proxy problem. Not sure how to fix the latter, but try running with your firewall of as a test to see if that fixes the issue - otherwise I will try and post some more ideas tonight

I am on my phone phone and can't access the links, but is the launcher crashing or is minecraft crashing. It sounds like minecraft is crashing, not the launcher in which case it could be one of the mods not working correctly. Try the developmental build without optifine and see if that helps, it worked for me.

Go to the minecraft wiki and search for lwjgl upgrade tutorial. It runs you the process of upgrading the files you are after. I have the same problem in the launcher so I don't use it. I would post a link but I am on my phone.

The value in the launcher sets the max mem value, in java it only uses what you need varies from 120mb and up depending on what you do. Optifine actually recommends you only use 256mb as it performs better. Press f3 and see what the max allocation is.

try updating to java 7 and see if that helps, then check this: http://www.minecraftwiki.net/wiki/Tutorials/Update_LWJGL updating the light weight java game library is supposed to help fix some issues

have you tried updating the light weight java game libraries LWJGL i think it is called. The minecraft wiki mentions some problems with the 64bit files on some PCs; i think they have a section that might help: http://www.minecraftwiki.net/wiki/Tutorials/Update_LWJGL Also i think getting java 7 might help - it looks from the crash log like you have java 6 still.

All the rest of the mods have different block ids and item ids as well - so it is not just EE that breaks things.

Pretty much all mods have a config file in the \config\ folder. You just need to find out what mod uses the block in question and then edit the config file for it. The technics pack is pretty full though so you may need to use not enough items to find the block ids that are free.

I got it working last night without optifine, but it was complicated. To make sure everything worked I had to remove optifine from the modpack jar file then reinstall all of the technic mods that are installed in the jar; about 6or7. Works just great now. I love the new launcher but hope they add the option to remove optifine eventually

The mod button on the launcher does allow you to turn off mods, so if you want to free up blocks it is great. NEI and the mod loader.txt file will allow to work out the conflicts and turn off or change the mods as necessary. The mods that are not optional don't conflict any block ids so they hardly matter unless you have key binding prolems

- edit - I think i have found a solution to remove optifine and the better grass fix I will test it today and post the changes if it works - end edit - I am having the same problem, the error i get after removing the optifine class files and changing the setting to false (or removing the option entirely) is: Minecraft: Minecraft 1.1 OS: Windows XP (x86) version 5.1 Java: 1.7.0_01, Oracle Corporation VM: Java HotSpot Client VM (mixed mode), Oracle Corporation LWJGL: 2.4.2 OpenGL: Quadro NVS 160M/PCI/SSE2 version 3.3.0, NVIDIA Corporation java.lang.NoSuchFieldError: cfgGrassFix at ModLoader.init(ModLoader.java:838) at ModLoader.AddAllRenderers(ModLoader.java:189) at afq.<init>(afq.java:80) at afq.<clinit>(afq.java:9) at net.minecraft.client.Minecraft.a(Minecraft.java:316) at net.minecraft.client.Minecraft.run(Minecraft.java:624) at java.lang.Thread.run(Unknown Source) --- END ERROR REPORT 6dd27f5f ----------
