Import of PowerPivot Model to PowerBI leads to unexpected error

[Skype]

Hello,

I am having this error when I am trying to import my powerpivot model to PowerBI.
It says:

Unexpected error

There has been an unexpected error while importing the data due to an error in converting into tabular mode (I translated the error)

With an older version of my model it works without problems. However, I do need the current version and it would take me ages to do everything again.

Has anybody had a similar error and can give me an advice on how to solve this?

I would certainly use the "send a frown" feature, so the Power BI folks can take a look.
