datasource verify all error since hotfix with CF8 and CF9

Hi,

On CF8.0.1 and CF9.0.1 since applying hotfix:

http://kb2.adobe.com/cps/907/cpsid_90784.html

Selecting verify all connections in CFadminUI Data & Services > Data Sources gives an error:

There was an error accessing this page. Check logs for more details.

CFadmin UI > Debugging & Logging > Log Files > application.log > reports:

There was an error while verifying the token. Either the session timed out or un-authenticated access is suspected.

C:\ColdFusion9\runtime\logs\coldfusion-out.log reports:

Warning [web-16] - There was an error while verifying the token. Either the session timed out or un-authenticated access is suspected.

C:\ColdFusion8\runtime\logs\coldfusion-out.log reports:

Warning [jrpp-3] - There was an error while verifying the token. Either the session timed out or un-authenticated access is suspected.

Why won't all datasources verify since hotfix?

Thanks in advance, Carl.
