I am not using it with Matlab, but quite extensively with C#. The somewhat strange error message you noted "Object is static" has always been an error in the script.

When I am sure that the script works Ok when run separately, it frequently has to do with the current directory being different when run with RDCOM and from GUI. Therefore I explicitly set the working directory at the top of all scripts, or get is from an environment string.

The most helpful tool is a character device in my application that outputs the R string directly, so I immediately see what the cryptic "Object is static" means.
