I'm having an issue regarding a game I'm attempting to reinstall on my computer. The game was purchased from the authors.(Track Mania United Forever) Key login numbers were sent. This was then plugged in and the program worked fine. After a matter which caused me to have to uninstall the program and to then reinstall the program, I have encountered an issue which states that the login key (provided by the company) is invalid. I wrote their support team and they then promptly sent me a new login key which in fact, does not work either! (invalid login key) I have checked all necessary login user names have uninstalled the program and reinstalled it. have tried the original login group of numbers. are there things that could be tried to bring about a resolution? Thank you very much!
