E-Licenser Control Error

I am sorry if this question has been asked…But I have not been able to find an exact solution for my issue and I have searched high and low for the answer. Here is my setup and my issue:

I am using:

Macbook Pro 13"

Mac OS X Maverick

Logic Pro 9 (Most Up to date version)

My eLicenser USB has 3 REFX licenses on it (Metrum, Multiband Sidechain, & Nexus 2)


I have been using these plugs with my E-USB for a while with no issues, but now out of the blue I receive this message:

  • E-Licenser Control Error

The Key Could not be Identified:

The Format of the Key is Invalid *

I use the most up to date version of Logic Pro 9

The only plugin in Licenses I have on the e-licenser are by REFX (Metrum, Multiband Sidechain, and Nexus 2)

If I open the project and click on any of these plugins the Logic session crashes and the error message shows as follows:

Strange, not had that before.
Does the eLicenser application show the licenses on your USB key?
