ISM Repository Error

I am trying to export a RAM model to Revit. The process runs just as described in the Ram Manager User Manual, section 3.2.2. The structural sychronizer opens and I don't make any changes, I just click, "Update Repository" and I am prompted to write a commit message, I do so. After this process I get the following error message: "Error occured during link execution". I have included a screen shot of the exception log.

Do you have any thoughts on why this error may be occuring?
