BlackBerry 8100 OS not working

[swordsjandl]

I recently purchased a Blackberry 8100
It worked fine Friday.
On Saturday it appeared to freeze./lock up, in that the screen went white and has an hour glass spinning in the center.
After a few minutes it cleared and returned to the main menu.
All appeared fine.
On sunday morning it again reverted to the white screen with hour glass rotating.
From my research I think I need to reload the OS for it.
I downloaded the device manager, from blackberry.com, to do so. The application said that it installed properly, however, I do not see the actual application anywhere on my computer.
Am I doing something wrong?
Does anyone know of a place that i can purchase the OS on a CD?
Thanks for any help and suggestion ya'll may have!

If you have recently purchased the Blackberry then I would recommend you not to R and D with it but replace it as it will be in warranty and it will be covered. However, if you do any physical damage to it then the warranty can be void.

DON'T Delete anything from the install folders other than the vendor.xml file.

Follow these instructions... is all you have to do:

Instructions for loading an OS (beta or official.)

(Make sure the device is NOT connected to the PC until instructed.)

1. Download the OS to your computer.
2. Install the OS by double clicking on it. Vista users, right click on it and select "Run As Administrator."
3. Browse to C:\Program Files\Common Files\Research In Motion\Apploader and delete the vendor.xml file. Do this regardless of whether the device came from your carrier or not. Again, it has no effect on what apps or how the OS is loaded to the device. It only determines "if" the OS is loaded. It doesn't hurt to remove it and I recommend removing it as a matter of habit.
4. Plug in device and browse to C:\Program Files\Common Files\Research In Motion\Apploader and double click on Loader.exe. Follow the on screen instructions.
5. (For BES users only) Contact your IT department for an Enterprise Activation password and enter your email address and the password in Options >Advanced Options >Enterprise Activation.
