I damaged my desktop manager installation disk. I have it downloaded on my desktop,but can't download it on my laptop. I tried the bb website,called at&t,downloaded it again. It either stalls,or doesn't install at all. I have a BB Curve 8310 ,OS 4.2. I am using an Acer lap top operating on Windows Vista. I am using IE. My son is away @ college and I am new to all this!!!!
