How do I delete old plugins from cache?

[VictorSteiner]

While trying out a lot of different versions of the Battletech Plugin I deleted the old plugins but they still show in the plugin-choose options. How do I get rid of those? Seems to be in a cache of some kind?

From lackey's main folder:  \secure\Preferences.txt, open it, and you should find lines at the top like " PLUGINNAME1:magic " and etc.  Simply delete the ones you don't want and fix their numbers after PLUGINNAME so it's descending without any gaps (0, 1, 2, 3, etc).
