FSX:SE Unresponsive during Weather Update

FSX:SE
FSUIPC

After multiple tweaks to the download/mileage/time settings at either 31 or 51 minutes from takeoff the sim freezes. One of the times I caught weather updating but the other times there has been no update and was getting the green bar with weather info and no freezes, a little stuttering.
Its always been with PMDG737NGX haven't tried it with another aircraft, but it previously worked on an older install of FSX:SE with no problems.

No freezing when using sim basic weather and the NGX.

When it does freeze I can't get back to desktop to see the log in the app so can't post what's happening at the time of freeze.

Thanks
