[MrHammy112]

I am re-uploading this because i can't edit my last post to put the log in for some weird and random reason. 

 

 

I have Minecraft Forge Universal 7.7.1 (LATEST) and when ever I attempt to launch my minecraft FML does its thing and seconds later it comes up with "FATAL ERROR OCCURED WHILST LAUNCHING MINECRAFT AND FML" and now i can't play minecraft with the mods i wan't 

 

so if anyone can help i would appreciate it ALOT!

 

 

Thanks.

Keep an eye on how far it downloads to. Mine kept crashing when it got to downloading the scala-library but eventually got past it. The only option I know of is to just keep trying. Now that I also have multi-mc I can see why it crashes too: it keeps saying that the connection reset (I assume it means the download connection). Fortunately with multi-mc if you try again it'll just resume the download right from where it crashed so you can effectively "brute force" download it. With the standard launcher it starts the whole download process again so it's more down to luck as to whether it'll work or not as far as I can tell.
