Unable to obtain a 2015 Autodesk license

Answer

If you are receiving a 0.0.0 error message when attempting to open your 2015 Autodesk product this will relate to the version of lmtools running on the network license server. You are advised to update to version 11.12 which is available for download from the Autodesk  site http://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/Latest-version-of-the-Autodesk-Network-License-Manager.html
