[Tekkit installation help]

Gave it a go but alas it still doesn't work. Can't work out why it worked before (although a good year ago) and doesn't work now. Any other suggestions?

I will give that a go, cheers!

[Tekkit installation help]

Not sure this is the correct place to post this, so excuse me if not. I have tried to install tekkit and I am getting an error message every time I try to play the game. It appears just after I press log in, there is a small window in the top left that then goes into the error. Minecraft 1.5.2 works absolutely fine, and I have successfully run tekkit before on a dedicated server on the same computer. I have looked through the internet and cannot find anything that works. I have tried installing minecraft version 1.1 and then installing tekkit, running a graphical patch for 128x128 resolution, deleting the files of both minecraft and tekkit and reinstalling (many times!).

I hope someone with a bit more understanding can figure this out as I have exhausted my limited knowledge. Also hopefully this is the correct way to upload the information from the crash report. Thanks!
