I have been playing two accounts on one computer since June. For the last few weeks I have been getting error messages when I go to log onto the second account. As soon as I click "OK" both windows crash and disappear. Sometimes a "report a bug" window pops up but not often.
It says "Wizard101 Error"
Initialization error: Direct3D renderer creation error: OK
I have ran the Dx Dialog and sent that in before and was told there wasn't any issues with it.
This sounds like a good question for Mr Lincoln! He'll know what's going on - just send him a quick email to support@wizard101.com with the information you posted here.
