[My launcher will not load modpacks]

Ok it did work for me before so I guess I forgot that the RAM would be used up for anything else. Since I had other things opened it stopped working for me. I'm so use to having 900 MB's of RAM having 15GB's of it went straight to my head. Thanks for the help.

[My launcher will not load modpacks]

How about mine? I have the same problem but haven't updated anything since I last opened up the mods a couple of weeks ago.

"OK when I launch any of the mods I have it won't load. It just flashes then goes back to the tekkit launcher. You said to delete the red files and put in the ones you gave a link to in the mod folder. When I went to do that I didn't find any of those files in the folder. A few weeks ago I opened up a few mods with no problem also updated some of them, but now they won't open at all. I have over ten of them and none will open. I looked in the error logs and they say not enough ram. I have the 64 bit java and set my ram to 15 GB's! Here is part of the error report. Some of it I don't understand why its even saying it. Like why is it even saying in 32 bit mode when I only have 64 and set to 64? I haven't changed anything up a few updates that I had for some of the mods since I opened them up a couple of weeks ago so I can't think of anything that has changed. Yes I tried reinstalling the mod too. Not sure what or how to check swap backing storage is or if its full.
