Need help with major Treo 650 problem!

I was downloading 3rd party programs such as games and a TV remote for my palmOne Treo when I came across a program that said it could increase the palm's performance and reactivity time. Now this phone is already fast and I didn't need it, but I figured faster is better right?

After I HOTSYNC'd the file over to the phone I pressed the icon and the phone rebooted. I figured that's what it was suppose to do. Well now all it does is load the palmOne screen, then goes to the "Palm Powered" screen, and shuts down and does the same thing OVER and OVER again.

Is there a master wipe I can do to clean the phone?
Is there a combination of buttons I push to reset the phone to factory?

Also, when I looked AFTER I installed. It said the program was NOT compatable with my Treo and it may cause crashes or other problems...
Damn! LOL

PLEASE HELP... I need my cellphone to work!

UPDATE: I found the RESET button and was positive that it would solve this. However after using the RESET button over and over again, it still will not solve the problem!

To reset the 650 to original configuration, hold the red phone button (hang up button/power button) down and use the stylus to pusth the reset button on the back of the treo.

Hard reset, wiping the device. Prob need to rename the backup folder to not bring that program backin again.

soft reset: hit reset button in back, or take out battery

warm reset: take battery out, hold down up on 4 way navigation while putting battery backin, once you see palm powered release button

hard reset: same as warm reset but hold down red power button

Prob have to rename that backup folder before you hotsync, so you dont sync that program back in device.
