Nothing there... Someone said to me i should reinstall the latest hotfix... but there is a problem too... i can't reinstal it, it doesn't allow me to do it... it just quits the program...
I'm no add-on manager expert but you have multiple instances of the import plugin (I have a single in and out)
Maybe you could manually delete them from the add-ons folder on your system? - and then re-install ... however I cannot say if this will cause you more problems.
if someone else with more experience with this can advise .....?
