Error from the start on Compute

Hi,
I have watched the tutorial on how to Run a Virtual Wind Tunnel with Compute and downloaded the demos to try out. I’m using grasshopper (1.0.0007) on Rhino 7 (7.12.21313.6341). However I ran into a problem on the start and I could not figure out how to fix it. The log-in seems to work fine, but something happens on #1 as shown on the screenshot:

“1. Unexpected character encountered while parsing value: F. Path ‘’, line 0, position 0.”

It might be a really small problem since I’m very new to script, on rhino/ grasshopper. I would really appreciate the help.

Thank you!
