i have the same issue with my blackberry 8900, installation performed okay, and i found it in my applications but couldn't view in themes, if anybody have the solution please share with us

having exactly the same problem.. installing done.. but themes cant be seen.. although it appears on the applications list.. tried restarting the device and pull out the battery but still no good..

help anyone?

at last , the info i need

Same damn thing here.. The application is installed correctly but I can't see new themes in Options. Themes. HELP Come on...

Try this

Go to Options>Applications. When you open the advanced options, you are going to see a list of every one you have loaded onto your BB. What you are going to be looking for is something that is labeled either the name of the theme(s) you loaded (Eg: Superman, Simpsons, etc), or something that looks like: plasmic_com.....04.15.2006.3423...Something similar. Not that exact writing, because they will vary by theme.

Now scroll down to it and click your trackwheel. A menu will come up. Scroll to "Edit Permissions". See that one that is set at "Custom" and the other 2 at Allow? We need to change that. So scroll to where it says "Custom" (probably under Interactions), click your trackwheel, and change it to allow. Now SAVE your settings! Exit back out to the main menu. Now reset your Blackberry by doing a hard reset. This can be achieved by taking the battery out for 3 seconds and putting it back in. Your Blackberry will now reboot.

Once it has finished rebooting, go to Options>Themes...And there they are! WOO HOO! You're new theme(s) are ready to use!

Nice sharing,thanks
