[1.48] Windows 8?

Well, i haven't been here for a while. I haven't played minecraft for quite a few months, and now that I'm playing a bit again I want to play computercraft. Unfortunately, when I try to run the mod after getting forge installed, it crashes at startup. The wonderful people over at mojang have made the client produce this lovely little crash log that i'm told to give to anyone that i report the crash to. So my question is whether or not it is crashing because I'm using windows 8, or because theres a bug in the system?

I know it isn't a startup error with Forge because that starts itself up fine. I have not tested any other mods.

I do, if you want I can screenshot my desktop where it says windows 8 Pro build 9200 in the corner. I don't know why it says windows 7.

I had to run it again since I tried other mods. Redpower Core works, though control doesn't.

Try installing your Minecraft and Minecraft forge again. Can't see anything we are doing that is causing that.

It'll be windows 8, it's still reletively new and not everything's supported yet

the crash log says that the computercraft files gives errors

Try downgrading Forge a few versions. I think I saw this crash somewhere else.

Try installing your Minecraft and Minecraft forge again. Can't see anything we are doing that is causing that.

It starts up now, haven't tested it yet though. I'm hoping to get redpower fixed as well, because that still crashes.

I play on Windows 8, and I can't see how on earth your operating system would crash your game.

I play on windows 8 on a mac, everything is perfectly fine for me, except for occasional crashes made by RP2. Try updating forge to the latest build, instead of the latest recommended build.

Tried updating Java, helped me once.
