Hi there!
I’ve been using Blender for years now, and I recently reinstalled my pc(windows), only to find out that I can’t get the program to run any more! 
When I start it up, the blender.exe window immediately prompts:
‘import site’ failed; use -v for traceback
sys_init:warning - no sitedirs added from site module.
Then windows tells me that an error has occured in blender.exe and that it has to be shut down… Help me :)! I want to be able to use blender again!
Any ideas?
