Hello,
After installing Forge for Minecraft 1.5.2, I started it with no mods just to check if everything went right.
Everything seemed to be great, but then minecraft crashed...
In the attachment you can see two crash reports. The first thing is the full error report. The second thing is the text Minecraft showed me.
Thanking you in anticipation!
