I see you are on the DEV update level. So he will update to the latest dev version. So it's normal that you can have a crash.

It' s maybe better to change to another update level?

As @@Sven suggested, change your update level.  Also I would suggest that you download the server setup again (choose beta) and run, it's important that you download the setup from the website each time you need to run any of the setups and not run an old one stored on your computer.  You will not lose your setting but it will ensure that a more stable version is installed.

 

Let us know how you get on

If you could test this on the latest server dev build that would be helpful. Thanks.

You upgraded to what and the problem remained?

The latest beta..

Updated + recreating library's = issue remained. So I ripped it out from the roots, complete uninstall + revo uninstaller to get a few left over reg keys + delete any/all mb related folders. Started from scratch with v3.0.5421.0  not surprisingly that seems to have solved it. (sorry for not getting back sooner, boards should be set to subscribe as the default for the thread starter)
