How do I upgrade from Crypt Guardian 2.0 to 2.5?

The preferred method is to run a backup of your data in version 2. (Backup and Restore Crypt Data option) Save the zip file in a location where it is safe and won't be lost. Then uninstall Version 2. When that is done re-install with one of the 2.5 install files (unzip first). After the install and settings are done run a restore and import the Version 2 data. (Using the password you used on the backed up copy from 2.0)  Restart Crypt Guardian 2.5 and all your data should be intact. See FAQ below for possible sound options fix. Some screen and grid settings will need to be reset and saved.
