i have a blackberry 9810 and i keep getting "application error 104" i have to select ok to continue a couple of times before continuing, please help.

I would check to see what the last app that you downloaded and installed. Tough one to figure out with the information you provided. I would say uninstall the last app your installed.

You can also try restoring from a previous backup.

Also try a battery pull.

And also: Application Error 104
