Ones I am downloading are highly rated(sure that wouldn't happen if it worked right), like medicraft, and/or have comments and reviews that say rather clearly that it works just fine. Don't think it is crappy modpacks. Plus my computer works great with games(Play on a heavily modded server on the other side of the world, only get a little lag) so I am not sure it is that, either.

Thanks in advance.

Whenever I try to download custom mod packs off of the technic site, the pack downloads correctly, but when I begin to play, I only get vanilla Minecraft. I was wondering if anyone else has this problem and/or has a solution to it, since I don't know how to work computers.(I am so spoiled by automatic installations XD)
