Hi! First off, I haven't got an error report, so I will try to explain the problem as clearly as possible.
I have tried this on my windows XP and windows 7 computer and had it fail the same way. I've tried multiple times on each. Both are updated to 1.2.5, and have fresh minecraft.jar installations.
First, I try to install Risugami's Modloader: I am installing v1.2.5. This part of the installation seems to work; I delete META-INF from mincraft.jar and drop in the Modloader files. Minecraft opens normally, and a "mods" folder appears in the .minecraft folder.
Next, I try installing MCForge. I have tried this with 0.94 and 1.05, and neither have worked. I take the files from the .zip and drop them into the minecraft.jar folder. At this point, minecraft gets stuck on the loading screen and will not open. it's the brown dirt background with a green load bar. It gets stuck at "done loading."
If I try placing the industrialcraft mod into the mod folder anyway, minecraft either hangs up exactly the same way, or gives me a crash report, but closes the window before I can grab it.
I have also tried exacting the .zip files and copy/pasting them rather than dragging and dropping from the .zip files.No difference.
Last, I have been using winrar.
Any help or suggestions? Thank you for any help in advance.
