How many issues were fix with 1.1 from 1.0 and are coming back on 2.0? Do we need 2.1? I don't have any doubt that Microsoft is going to release 2.1, actually they planned to do so before they ever ship 2.0. I have been finding a few issues that I haven't seen since the 1.0 version.

Now in version 2.50727 I am looking at the new exception:

So, I look at the old support pages on 1.0 to fix it without much success:

I have also created a machine name still with the same result :-(

The only solution that works is to disable the ViewState and find another way to store the data between requests. I'll be writing a solution, so keep an eye on this blog if you are having the same problem, also you are very welcome to post your exception here.
