I'm sorry but, since GSX obviously work very well for everybody, and you came here on the forum saying in public "it doesn't work" and your experience was "horrible", since this is not clearly the case for the vast majority of users, then yes, you MUST go through the proper troubleshooting process which is:
Provide a precise and as accurate possible description of ALL the issues you found, and I can assure you most of them would have an explanation or a solution and are very likely covered in the manual.
We'll to through them, one by one, and a refund would be considered only if we FAIL to find a solution. I will anticipate, this will never happened: we always find a solution so, I'm 100% sure after your report, we'll let you use GSX properly.
