first off, make sure you have the latest version of forge!
also if you have any other mods, take them all out to see if they're conflicting with it, if it works, keep restarting and adding them back in till you find the bad mod, then dont use it
The bad mod is Daley mod U45 should I try updating java
Also,post the crash log if there is one,as it'll allow us to see the problem.
List all the mods you have too so we can see if Dalek Mod is conflicting with one of them.
no crash message just says Minecraft has stopeed working then closes minecraft!
I have Optifine and Dalek Mod U45
