Shaft Generator can't create parts any more

[Anonymous]

Hi,

I'm using Inventor Professional 2014

I created several Parts with the Shaft Generator, and from one moment to another it always says that it can't update the part file with the new shaft when I press Ok. 

Here is the original error, I'm german, so of cause its in german, but i discribed above what it says:

******

Komponente C:\Users\Manuel\Google Drive\Projekte\Eigene Übungen\Test2\Konstruktions-Assistent\Welle1.ipt konnte nicht aktualisiert werden.
Welle konnte nicht erstellt werden.

******

Someone knows what to do?

Cheers

Found a way to solve the Problem:

I just deleted the folder  C:\users\"current User"\AppData\Roaming\Autodesk\

And now it's working again. 

But I still don't know what happened.

Cheers
