If you have completed the steps to import and assign the keys to the resource according to the guide (page 999 and page 74 respectively(in version 5)) then I suggest you gather more information by creating a simple project so you can get a debug log.
Below are the simple steps to follow for this. Once you run this test project, if the job log doesn't clear up the issue, send it and the project to firstname.lastname@example.org
with the case number 36738 in the subject line. We can take take a look and let you know what we see.
For the project: While in the project, click on SHOW XML, then copy & paste the project to an email.
For the log: Click on the Main module on the upper left, then click on the Control tab on the right and select “Debug” in the Log Detail box. While in the job log, at the bottom of the job log there will be a button tabled DOWNLOAD JOB LOG. Save the job log to a file & attach to the email that you send to support.
