I got some problems with Adobe PDF Reader. I cant open any files, the error message is "Some objects is not identified. Could not open" and then its just shows "Drawing" for 1 minut and then I get USE-EXEC blablabla and It shuts down. I tried to reinstall it but nothing gets better. I´ve got a 9210i !
Try installing all the available fonts from the CD (onto your memory card). I have had similar problems with other apps, and once I installed the fonts, all was gleeful.
