Have you checked to see if your MultiTerm application is also up to date and on the same version as Studio?

Have you tried to reorganise your termbase in MultiTerm?
Instructions are here

Let me know if this helps or if you require further assistance

Are you using Rapid Add Term? Or are the language names in your termbase different from the names in your project? This could happen, if you add your termbase with for example language names in English to a project, where the language names are in German.

Hi Lydia, my apologies, I didn't receive notification of your answer until I opened the Community to check just now! I have checked that both Studio and Multiterm are up-to-date, but will try and reorganise my termbase now. This was a termbase I've been using for a long time. I've been working on a project with a tight deadline, hence not checking back earlier, but had thought it was working again. Now I've switched to a new project (with an existing termbase), it's not working again, either Quick Add or just Add new term. I'll see if reorganising the termbase makes any difference and report back.

Best wishes,

Claire

Hi Jerzy, as I said to Lydia, my apologies, I didn't receive notification of your answer until I opened the Community to check just now. Neither Quick add not the normal add term is working, and as far as I know the language names are corret as I've been using them without any problem for years. I'll try reorganising the termbase as Lydia suggests.

Many thanks,

Claire

Thanks, Lydia, that seems to have done the trick. There was one termbase that wouldn't allow me to reorganise it (I had the message 'an error occurred while parsing Entity Name1, Line 1, position 135), so I'm not sure how to fix that. I've removed it from the project for the time being and have just tried quick add term, which worked. Do you know how I can fix this termbase so I can re-add it?

Many thanks, Claire
