Little help with Sprite Backup?

[Wipeout]

I had high hopes, admittedly, for Sprite Backup with my PPC6800. I've read great things and I had used a previous version with my Axim. So, I purchased the latest version and installed it on my XP Pro machine at home. It backed up the device just fine. However, I am unable to open the backup file within Sprite Explorer. It tells me "invalid password or corrupt backup file". I emailed Sprite support, and after a fairly quick "glossing over" of the issues (what OS; uninstall and reinstall), they had me send them a backup file. After they
were able to open the file without issue, their answer is "well, the problem is on your computer."

Has anyone experienced this, or should I just return the software and get my money back? I'm a little hesitant to support a piece of software that has seemingly non-existent support.
