Menu writer just hangs no menus inserted.

Hi
everything was going well until I changed a menu to include some dynamic links and when included caused issues so I decided to go back to static menus to save time.

Menu writer lets me get through to the stage where it inserts the menu on the page starts the site tools then just says initialising and thats it no menu inserted.

Any ideas?

Like I said it was working fine in fact perfect the whole design extender was great until now.

Tried deleteing cache - uninstaling/reinstalling - restart pc still the same.

I really do not want to remove all extensions (renaming config etc) 80+ extensions installed this would be costly and extremely time consuming. Any other options or solutions would be appreciated.
