So listen to this… I have been having the serious issue of black screen on gem purchases and currency exchange and the issue of misshaped text boxes on buy and sell tabs… Very annoying. I was out of commission for about a week. After trying to reset the system, delete local dat file and reinstall, as well as deleting the specific activity monitor things… to no avail… I finally tried to install the guild wars 2 game on a program called CrossOver. Worked like a charm. Everything works fine now. I’m basically running a windows version of the game on my mac computer and TP works perfectly fine. Hope this helps.
