E-Gad, what am I doing wrong? I only want to try out the ZLauncher before I buy however, I can't get the thing to install. I Keep getting message- install error (FFFF) so I tried installing it on the M-Stick and I can get the main ap on, but then the theme won't install. Could it be that I don't have enough memory? Any ideas as to what's causing this. I may have to just leave my UX-50 as it came out of the box....I have been Hotsyncing wirelessly, could that be the problem?
