Please clarify the meaning of "The server threw an exception. (Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT))"

I am developing a C# Console application, that has nothing to do with the server but it does use a library vcamcomlib which comes with the trial version of e2e vcam.

These are my lines of code

refByte = File.ReadAllBytes(@"filepath");

vcam.PlayBuffer(ref refByte[0], 640, 480);//Exception comes here

My program was running fine yesterday, however i started my system today and trying to run it. the exception just showed up. Can somebody help? Thanks alot

From this URL, they discussed about the COM interop and thread safety. Better ask them which components are safe in multi-threading and which are not.
