Logitech Issues & Deleting Files (?)

Picked up the Logitech LX 700 Cordless Combo...

The CD from the box was useless, so I dowloaded from Logitech's site and before installing the software I was able to use most of the keyboard's features but not with the mouse (eg. Back Button)

After installing the software, the mouse feature's works but now the keyboard doesn't...I can't even use Start + L to enter a new address...!!!

Also, coming from Windows...how do I know if it's SAFE to delete files since there's no "Add/Rmove Programs" ???

Any input...???

Don't really feel like driving to Apple Store (Yorkdale Mall)

When you want to delete an app that doesn't have an uninstall program, just drag it to the trash. If it comes with an uninstall app it might be located in Utilities, which is where my Microsoft keyboard/mouse uninstall utilities were.

I had problems with my logitech mouse on my mini, everytime I would turn it off I had to reset the mouse sensetivity, very annoying.
