media upload addon Conflict with frontend editors

I purchased the media upload add-on for the comments and it causes a conflict with frontier post frontend editor and also tried a bunch of others to see if had same conflict.. and it does...  Causes the users not to be able to center their text, image and select font does not work..  Also when I activated it.. it leaves a message at the top of my admin page saying "Activate - " and that is all and stays there..  just the text shown.. nothing else...  Hence I had to deactivate it so my authors can publish as they wish...  If can't be resolved.. I am just out the money invested.. Otherwise love the comment system... But wanted the users to be able to add media to comments... Thanks John
