[SOLVED] Help needed: Can't export 3D models

I'm getting an error whenever I try to export a 3D model (copied at the bottom of the post).

I exported 3D models in S4S before without any problems, but I didn't play/create for a while and now it stopped working (importing models works just fine). I also tried exporting a 3D model with TSRW, exporting as .wso file works, but not .obj so I'm starting to thing my pc is the problem here. The only thing I can think of what has been changed in the past months is a Windows Update.

I'm working with Blender 2.7, didn't change anything compared to a few months back.
Tried with S4S version 3.0.1.9, 3.1.0.4 and 3.1.1.5 all give the same error

Anyone got an idea what's causing this?
