Also my Problem is when I start Pokemon TCG Online application on my Windows 7 system there is a Refresher Patch Update.
It takes many hours and it don't will end!
I have removed the Refresh Update Application and all other refresher data forever. Then I moved the Folder with the PTCGO Data in a other Directonary. I have restarted my PC new and would try it again. But It was the same Problem.
I've had the same problem. .... on Windows laptop AND on my mac. I did Control Panel, Programs, Repair... and that got me past the patch thing... but then the program doesnt launch at all. I'm uninstalling now... taking forever.
