Error running EPDM task

We are running EPDM & SWX 2013.

Just upgraded EPDM vault 3 weeks ago.

Tasks ran fine after Vault upgrade to 2013.

After installing SWX 2013 (the next week) the tasks no stopped working.

Error Message: Failed to run SolidWorks macro.

Error Code: E_FAIL, 'An unspecified error occurred.'

User permissions for the task are correct

Permissions to the folder that the PDF file is saved to is correct.

I am guessing it is something to do with Solidworks 2013 since the problem started after upgrading from SWX 2011 to 2013.

Anyone know what the problem is?

Gary.
