Hi paola,
i was on 2.06 before - it did not work,
just updated to 2.1.1beta - does not work.
I really have no idea, what could go wrong on my device.
I have already installed other third-party apps, e.g. pbchess and zwadrax, poterm and get_root - I am no newbie. But in case of CR (i tried it several versions before - and it never worked).
I can not find any kind of log file to help me understand, what is wrong, just the message mentioned in last post and back to menu.
