You can't save apps to the SD card, but that is likely not your problem anyway. I would pull your battery out for 30 seconds (or hold down alt-R Shft-Del all at once until the screen goes blank) and reboot your phone. If that doesn't fix the issue, I would also try deleting the application, rebooting the phone again, and then reinstalling it. Make sure that the application is the correct one for your operating system and phone, as that will also cause error messages.
error starting biggest loser symbol deviceinfo.get total flash size not found

Your BlackBerry can only run applications designed for use on a BlackBerry. That error message could be looking for Adobe Flash, which is not yet supported on BlackBerry.
Thanks, the Flash reference confused me. It must be a reference to the internal Flash memory which is different from Adobe Flash.
I would suggest deleting the version you have now and repeating the download. If it still does not work, the problem is likley internal to the program, only the original developers can correct that kind of problem.
It should prompt you when you install it. When it does, click view, then back, then save (you shouldn't have to change anything, those are all the defaults when the menus pop up).
I am having these exact same problems with this biggest loser app. I've even tried re-installing it (but didn't delete the first one because I didn't know how--or where to go to do this). I am curious if other than myself & the original poster have had these same problems and if anyone has been lucky enough to get this app to work. Thanks
