When starting the local server i get this error.

I have tried to uninstall and re install odoo, have stopped en started the odoo services in msconfig, but that didnot solve the problem..

System Windows 7 32 bit, Odoo 8.0.

I installed serveral add on, and i assume that is part of the problom. I am a bit of a noob, and don't kwow how to uninstall them or how to use log files to find the problem, so please try to be as specific as possible if you now a solution.
