I know that many people have never had a problem with this device, but I have to tell you it has been a nightmare for me. It won't properly install the software on my XP pro based computer. It gives me an error message ("Internal Error 2762"), then asks me to reinstall. I disabled all the antivirus software before I tried it, so I took the Pronto Edit software out, restarted the computer and tried to install with the anti-virus running. Same error. Since there is a repair mode, I tried to get it to repair the install, but it wouldn't. It gave me the same error message. I tried to change the installation, but it gave the same error message. I took it all out again, attatched the device to the usb, restarted and reinstalled...Same message. I decided to download a new version from the website. Since you have to register before you can download, I tried to, but it gave me an error message - several tries, but always the same message. I'm not an amateur at loading software (do it for everyone I know because they end up with problems so they call me). If I didn't have to go to work a 12 hour shift tomorrow (actually today, but it's 5:00 am and I don't have to go till 7:00 pm), I'd take it back. Instead I'll wait for my days off. I'm certain noone else has run into this kind of a problem, but just thought I'd share it - keeps me from firing the thing across the room and into the wall.
