help & bug reports (non-modded)

Please help us!! We've been trying to solve this issue for about 3 months ever since the 1.5.5 update came out but nothing works... :frown: We have tried: -Reinstalling the game -Restarting their PC multiple times after each step -Deleting startup-preferences -Repairing the XNA file...

after the update my game doesn't want to open anymore, i updated my drivers, i already switched to beta and it still stays open for 10 seconds and it closes by itself i even checked the task management and it closes by itself so i don't know what else to do, i play alone, when the 1.5.6 update...
