CRRT8500E: Server Error: Problems deregistering sandboxes
![](http://jazz.net/_images/myphoto/d9cab087e0286be8236b0e0286dd0849.jpg)
We have sometimes the following problem with the VS Studio client
We have VS Studio 2010 with installed RTC Plugin (4.0.1). Sometimes, when we try to change the sandbox (right-click to another sandbox and choose the option set as current sandbox) we got the error message CRRT8500E: Server Error: Problems deregistering sandboxes. When we try to change the sandbox again, it works.
Unfortunately I didn't find the error message in the ccm log.
Is that a known problem or did anybody know why this happens? (e.g. lock of VS Studio)
Accepted answer

Unfortunately this problem is not jet solved. There is a defect work item for that issue. At the moment it is planned for 4.0.5. (but it was already moved from 4.0.4 to 4.0.5)
