   ref paramMissing, ref paramMissing, ref paramMissing, ref paramMissing, 
   ref paramMissing, ref paramMissing, ref paramMissing, ref paramMissing, 
   ref paramMissing, ref paramMissing, ref paramMissing, ref paramMissing, 
   ref paramMissing, ref paramMissing, ref paramMissing);

And i am recieving the error Attempted to read or write protected memory.

I'm pretty sure that all those paramMissing reference arguments are your problem.
