Try the "Installation/Support" section or send Admin a PM. I suggest posting to/searching the forums because if you are having a problem, probably someone else is too and finding the solutions here by doing forum searches is productive. If the answer isn't already out there, and you post about your and then a solution is found, then the next person coming behind you will surely appreciate finding it.

I'm sure Admin can provide personal support, however (and I can't speak for him/her, only myself) it must be difficult to provide personal support for all users of this script and he/she probably appreciates if people try other avenues before contacting them.

I have not experienced any problems with the upgrade. It's possible you missed something during the installation of the upgrade?
