OG Forums not uninstalling correctly

Hello, I installed OG Forum but I forgot to change OG module, so I changed it, but I wasn't sure if there wouldn't be problems, therefore I uninstalled OG_Forum (og_term on database was deleted but there was an error, so I think the variables were not) That killed my Forum module so I uninstalled Forum and installed again. Then I installed OG_forum once more and everything seems to work ok, but all the data is of course gone. There was no way to import the Forum database portion again (at least an easy one way)

Please change the uninstalling code because it could destroy a Drupal Forum.
