not a legal oleaut date - cannot refresh

[AlexanderAT]

Hello

I'm having a problem refreshing my report online. Everything works fine on the desktop version where I can easily update my dataset, but when uploading it and trying to refresh I get the following message:

Last refresh failed: 

Data source error:	Not a legal OleAut date.. The exception was raised by the IDataReader interface. Table: ProfileScore.
Cluster URI:	WABI-NORTH-EUROPE-redirect.analysis.windows.net

I have read the other post with the same issue but those solutions do unfortunately not work for me.

Anyone know how to fix this error? 

Thanks
