Created a new reply so you can get a notification. Also I didn't see that I needed to upload my attemp.
So, I want to get a simple modpack and a server launcher of it.
First I tried without reading/watching any tutorial.
Then I tried your tutorial. It didn't work (download link)
Note: I created my own modpack.jar file and downloaded a modpack and tried my modpack.jar it worked, then i added the mods. When I launch, it freezes in mojang and it says "Not working". Tried it 3 or 4 times and nothing I even waited like half hour and still frozen.
MineCraft 1.4.7
Modpack name: alexmodpack
Mods:
-Tekkit Lite modpack (found in technic launcher)
-Mo'Creatures - http://www.minecraftforum.net/topic/81771-152-mo-creatures-v523-with-raccoons-ants-mini-golems-silver-skeletons-and-more-fish/ (there is 1.4.7 there)
Thanks!
