Here's a challenge:
Play tekkit on a server you never played on for two weeks, than record it and post it.
you can do it with friends or alone.
I did it so here's a video:
Ip: play.tekkro.com
How to fix :
delete all java files
tipe in google ''download 64 bit java''
install and reinstall tekkit lancher by deleting the .techniclauncher folder
set the allocated memmory to the max
you are now able to play tekkit for more then 5 sec withouth a crash !
