[R] LaplacesDemon.hpc parallel prosessing problem

[Journals]

I have a problem with the LaplacesDemon.hpc which terminates with an 
error. I am not sure if this is in the parallel or the LaplacesDemon 
package. And if it is a unsuffiency of my code or of the packages.

The code runs WELL as NON paralellized code.....

 > Fit <- LaplacesDemon.hpc(Model, Data=MyData, Initial.Values,
+                      Covar=NULL, Iterations=31500, Status=3000, 
Thinning=210,
+                      Algorithm="twalk", Specs=list(SIV=NULL, n1=4, 
at=6, aw=1.5), CPUs=2)
