Tekkit crashes on start-up (1.2.9i)

[TheFlyingBaboons]

So, I last played Tekkit back in April and everything was fine

I decided to get back into it now, and it crashes on the Mojang logo screen

B:allowUpdateCheck is set to false but it gives the same error even if set to true

You can try deleting both the bspkrsCore and treecapcitor config files to let the regenerate (assuming there is one for each).

I do not know what version this is, and I would assume they are already up to date, but double check and make sure they are both the most recent versions.

Yes, I've tried that multiple times and also reinstalled the pack

And yes, they are versions 5.3 and R09 respectively

Based on other threads make sure LegacyJavaFixer is installed.

However turning off the version checker should already solve this issue, odd that you claim it does not.

It works now, but thanks for trying
