I got one of the vouch copies.. probably the first one to get..Initially had some trouble with the software but, after a few hours of diagnosing it finally worked.! According to OP the error was specific to my PC and not the software.. and if that is true.. He was patient and helped a lot to make the software work for my PC. Udemy has a lot of courses..some r really good n some r poor.. why pay for each course seperately while you can get the whole package for cheap.! I can vouch for this product.. it is working seamlessly now! thanks a lot Krejsx!
