MWS:Upgrading

If you are upgrading from an earlier release, the alternative that is least likely to cause problems is:

Start your existing Raccoon, open the settings and write down your Identifier and Password. This is an unnecessary step if you still have your original registration mail.
To be on the safe side, backup any custom HTML pages or Python/PSP scripts you have made.
Uninstall your existing installation and behave as if you were installing from scratch.
