RCG RC-XKE20017 USB Security Tool to Hide Directories and Lock Your PC

I have a X-Key with software version 2.0.0.25 and when I installed it on Window Vista Ultimate my iexplorer web browser started crashing immediately. To make sure it wasn't malware causing the problem I formatted my C:\ drive and reinstalled Windows Vista and all windows updates. Iexplorer was working fine with the fresh install until I installed X-Key and again iexplorer would not work. I decided to try installing Firefox and it seems to be working without conflicts but I really liked the layout of iexplorer and really didn't want to use Firefox but I don't have a choice since the RCG website does not have any software updates available for the X-Key and tech support has not returned my email in a week. BTW, the 15G of files that I had hidden on an external drive are not recoverable after I reinstalled the operating system on the C drive and installed X-Key using the same product code and login details.After spending many hours on this and losing my files with no help from RCG about fixing the incompatibility with iexplorer, I am frustrated with the lack of compatibility, updates, tech support, and information available about this product and give it a thumbs down.
