I've just bought the iPad versión and I have not been able to use it yet as it freezes in the boot screen. I've tried waiting, closing everything but PStouch, rebooting the IPad2 completely and so on, but nothing seems to solve the problem. My iOS version is 5.0.1 so i don' t understand where is the problem, in fact it's the first App that absolutely refuses to start in my device. After a long wait for this software I'm very frustrated, to say the least!
Sorry to hear about your difficulties. Please try uninstalling and reinstalling the app and see if that resolves the issue. Please follow up if the issue persists.
Try closing PS Touch and then restarting it. If that doesn't help - have you tried to uninstall/install?
Please let me know if it works. Btw did you have problems starting it from the beginning or did your problem occur after doing something specifically?
