Support Request: Crash (Invalid Entry Size)

! That might be the issue...I downloaded a new copy of the game, replaced the files for ModLoader, then tried to open it, but all I got was a black screen. Here's where I was downloading ModLoader from: http://www.minecraftforum.net/…-mods-everything-updated/

I scrolled down and downloaded ModLoader 1.0.0 using the AdFly link. As I wrote in a previous post, I followed the instructions on that first post in the thread to a T.
Also, here's the link for IZarc:

Seems that 7-Zip got it working! I re-downloaded everything, extracted using it, placed everything in the appropriate place, and all is well now! Thanks everyone, I appreciate it!
