Tekkit installation help

[SallyRebor]

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!

update your java and make sure your video driver is up to date as well, then give it another try

[SallyRebor]

I will give that a go, cheers!

[SallyRebor]

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?

[Magister]

delete tekkit and do a fresh reinstall
