LOL!! I think you mean the
simulator. Anyways, this has been answered in other posts, but I'll let you know here anyways.
1) Make sure you've downloaded the simulator from RIM. You can go to their website (
Smartphones, Cell Phones & Smart Phones at Blackberry.com), you'll have to fill out a form with some personal information, but the simulator is still free. You'll have to select which BB model you'll want to download from them as well.
2) After you've downloaded the simulator file from RIM, install it.
3) Make sure you've exported your theme from Theme Builder.
4) Then run the simulator from your start menu in windows.
5) When in the simulator program click on File and then load the Java Program. From there, select ALL the .cod files and then click open.
6) Restart the simulator. When it boots back up, select your theme from the options/themes.
Sometimes another restart is necessary for it to load the theme properly, but not in all cases.
Hope this helped.
