We have recently been notified of an issue where Xrev commands would fail to run at all.  After some investigation we discovered it was cause by the Project Information parameter “Author” not existing in a project.  This parameter should always exists, even the API documentation has a class specifically assigned to this parameter.

Regardless, this seems to occur if you start a new project or template without using a template (IE: you just use the metric/imperial prompt) option to get an absolute bare bones template.

We are currently working on the 2013 release for this version to tie people over until Xrev Transmit 2.0.  We apologise for the delays, but when the new version is released people will hopefully think it was worth the wait.
