NEWBIE- I read the Vista Rom Upgrade threads but still need help

[socom0240]

Hi, I have an HTC 8125, and I desperetely want to flash it with a WM 6 ROM, But I only have Vista, and I am having so much trouble following the threads on doing this with Vista, that I am going to have to give up if I don't get some advice. I have downloaded the Wizard Tool, but it won't ever recognize that my phone is connected, even though Mobile Device Center says "connected". I tried using the program HARD SPL G4, but when it makes the screen go white on my wizard, mobile device center automatically says not connected, and at that point even though I get the screens to proceed with the new Rom, they dont work because my phone is no longer connected and nothing that I do lets it connect to mobile device center while the screen is white. I have to reset the phone and then the rom update doesnt work anymore.

Please help, even if it is pointing me to a topic or post that I don't know about. I have spent 12 hours reading and failing over and over with this.

Simple answer to all of your problems is Vista,Do it on a WinXP machine there won't be any problems.
Although,its possible to unlock and flash through Vista,but its still not compatible,WinXP is highly recommended.
