I recently installed Vault pro 2013. I was running Inventor 2012 at the time.. My vault add-in stopped loading. I installed Inventor 2013 and the vault add-in still won't load. I've gone to the Add-in manager 2013 and set it to loaded. I hit the "OK" button and nothing. Open the manager up again and it says "unloaded". Something is going on that is not allowing my vault add-in to load. This is very frustrating. Any suggestions?
