Mochaimport+ 4.46 doesn't work with Mocha?

I upgraded to Mocha 4.1 and then upgraded Mochaimport+ to 4.46. But after that I can't get clips into Mocha by using the "Import Button" > "Track in Mocha". The script asks to make new oder overwrite the existing but it doesn't open Mocha. After installing 4.45 it works again, but it says that this was "created in an early version or so". What I'm doing wrong?

Cheers
