Sandboxed software having issues when loading certificates. Are there Settings regarding certificates?

[evoha]

Hi,
I am trying to run a server software inside Sandboxie. When I try to connect with the client software (started within the same sandbox) I get the error below.

--> Are there sandbox settings which affect certificates?

I trust the server and client software - there is no suspicion of malware. The main reason why I am using sandboxie is to have registry keys separated.

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Security.Cryptography.CryptographicException: The stub received bad data.
