I had this problem also at one time. To correct it I now rename all the install folders to each MVP complete mod to the season I used..MVP13 or MVP1958, and so on, I rename the folders and properties in the all programs list also and the desktop shortcut. That way you can have as many Mods loaded as you want. When I want one off instead of uninstalling I delete that years folders then run CC registry cleaner. Of course you can only save as MVP2005 in season, but I just move all my saves to renamed folders under there year listed then if you want to go back a different year you was playing you have a backup of the save you did, put it in the MVP2005 folder in My documents and you are ready to go.
