Crash White Screen Problem

[icedinc]

Hello, I was playing on tekkit classic the other morning, on my server, and everything was fine as usual, I came off the server for a little while, and now whenever I run the tekkit classic modpack, the Mojang screen loads, it takes a while, then the screen goes to the standard dirt background, it stays like this for about ten seconds, then a brief error message comes up thats too quick to read, then the screen immediately goes white and stays like it. This is really annoying me because I need to get on the server to be an admin. This problem is persistant and annoying and I would like help with ASAP. Thank you.

Did you try to reset the mod pack?

Try to backup your tekkit classic and reinstall a fresh one by deleting the old classic game data.

This is due to a corrupted player .dat on the server. You will need to ask the owner if he can reset your player.dat. That is the only way its going to be resolved. Good luck!

Hey People,

 

I recently downloaded Tekkit onto my laptop and it was working fine for 2 days, recently however whenever I try to open a world it goes through the normal processes of opening a world then it gets 'stuck' on saving chunks and after about 10 seconds of 'saving chunks' it then displays a brief flash of text then a white screen, the same thing is occurring on servers when I try to log on. I have tried re-installing java, re-installing tekkit after deleting the file folders, I have restarted my computer and I have tried to start a new account on my computer to try to get it to work. I don't have any clue what to do now. PLEASE HELP ME!
