AX2012 R2 - Client crashes when doing a TFS synchronize

I have an AOS and client installed on my laptop (Windows 8) which is connected to TFS. When doing a synchronize (TFS not DB), the client crashes and restarts which will result in updated XPOs in the local repo but nothing in AX.

The event log will record 3 errors:

Event ID 180:

"The description for Event ID 180 from source Microsoft Dynamics AX cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:

Options I have already tried:

- re-installation of client and AOS

- installed CU1 (still client crashes)

- installed AOS & client on Windows 7 and Windows 2008 R2 (still crashes)

- have deleted local repo, workspace and models and started again from scratch. Works but after some syncs client will crash again.

Does anyone experienced this? Any ideas?

Thanks,

Kevin
