Unexpected Error with session ID (with mashup text) when creating a dataflow

[Anonymous]

Hi All,

Wondering if anyone can help. I've been creating dataflows with no issues for the last few weeks. Suddenly yesterday they stopped working and I'm now getting the above error.

I've searched the message board and checked that I am admin on the workspace, I dont' have a gateway installed, as it's not needed.

Does anyone have any ideas why this would suddenly happen?
TIA
