I have just used the most recent update. When I open SubframeSelector I get the attached error message. If I click OK, close SS then reopen it, no error message occurs. In addition to this, the documentation won't open. I just get a blank screen without the common "Sorry, documentation not available"
I have an MSI laptop running W10
I have another computer running the previous version and none of these problems occur.

Note added: i have just downloaded the latest version of PixInsight to my second computer (Fitlet2 with W10), but not added the 3 updates suggested. SubframeSelector opens normally, and the documentation now responds with the no documentation message.
Another update: I reloaded PI and installed the latest updates. The same error message occurs, but the documentation is now available. I also fully updated the Fitlet and everything works as it should.
