Can't Play Solo in Studio... What?

I have two computers that I use. One works and the other is just being odd. I re-installed studios and everything but every time I go into play solo on studios I get this error and the solo freezes up. It started happening about a week ago and here is a picture.

If you want to zoom in on the image go here:
(Every time I go into a game it just puts in one random error message in a script.)

On the buggy computer, does Play Solo work on an older version?

I fixed it by turning off the script debugger…
