|Try downloading the trial version of the newest version 7.0.6 and unlock the drive, then uninstall the programs (or purchase a full version of the new one):|
The version you installed may not really be Windows 7 compatible, the new version may be able to fix that. I would recommend NOT using it to lock your drive, or you should keep an unlocked version as a back up in a secure location. See the publisher's support pages if you want to keep using it.
You have to be a little bit crazy to keep you from going insane.
