I am having exactly the same problem as described in this thread:
The issue appeared to receive a solution although that was done via private messaging for some reason and the solution was not shown on the thread.
I'd love to be able to fix the problem on my pc as well so if anybody knows what to do please help!
Ignore previous responder, that was spam. Please contact Technical Support if the problem still persists. Link under Useful Links at the top of this page.
