Is there Service Studio 9.0.0.1 or 9.0.0.2?

Is there Service Studio 9.0.0.1 or 9.0.0.2?

  
Are there Service Studio verisons earlier than the current 9.0.0.3, while still 9?
I didn't find them in Downloads.

I wanted to try downgrading because I can not open one of my core eSpaces in the current version, and according to error stack trace the problem is in studio itself. I wrote to support, but don't know how long will I wait for the answer, or especially the fix. The eSpace was created in version 8, and opens fine in it, but I need to upgrade it to 9.
I am afraid you have to wait. Did not spot an old version as well.
