All my Tradsos elements have stopped working! (TW Freelance - 2007).
I have repaired normal.dotm & trados8.dotm and refreshed in the file in the STARTUP menu. There I have 2 trados8.dotm files: One macros enabled (!) & one macros not enabled.
Make sure you have both Trados and Word closed to begin with. Go to the STARTUP folder and remove the trados.dotm file that is NOT macro-enabled. Only the macro-enabled file is required.
The Word add-on list shows trados8.dotm & trados_2.dotm, which both point to the above folder.
I have tried to de-activate the add-ons and to remove them .. but they obstinately stick in the list.
Does the trados_2.dotm file relate to the fact that you have "...2 instances running on 2 computers in a network"?
If not, then I presume that removing the non-macro-enabled .dotm file may remove the trados_2 add-in.
(I have had runtime error 5853 on Word - that is solved now) but there are still irregularities.
After doing the above, try opening Microsoft Word again. If the toolbar is still not there, go to Word Options > Add-ins and try re-enabling the trados8.dotm file. After that restart Word.
When I restarted word, I received the runtime error 5853. I ignored it by clicking End, as I couldn't find the solution like you did. After that, my Trados toolbar was back and appears to be functioning normally.
Hopefully this works for you too. If not, I'm not entirely sure how to resolve your problem, but SDL Support replied to another thread (that I have been unable to find again) with a link to an article on the SDL Knowledge Base that explained how to edit the registry to resolve the problem. Maybe you can try that if all else fails?
