It seems that all of the solutions on the internet for fixing the Runtime 6 errors didn't do a thing. I cleaned my registry, cache and temp. folder, and no change.
I have the same problem. I had run one of the user shop autobuyers from this site for hours and all of a sudden i get the Runtime 6 error. Then, after using this trainer for around 4 hours, i get the same error. I've reset my IPs, restarted my computers and even tried on different computers - still, same problem.
