Hello Clara Pérez Ferrándiz,

It would be good if you could explain exactly the steps you are taking and when the error occurs.

Perhaps post also the error stack/image of the error

okay, so when I was creating a new project, I tried to create a terminological database for that project; but not from scracth (here there is no problem). I chose createing a database using the option 'bilingual glossary' but then it says that there is an error and I can't create with that option.

First of all make sure you have the correct version of your software. We still don't know what this is (looks like 2019 or 2021), so check this:

SDL Trados Studio 2021 - 16.0.2.3343
SDL MultiTerm 2021 - 16.0.1.304

SDL Trados Studio 2019 SR2 - 15.2.7.2849
SDL MultiTerm 2019 - 15.0.6.56482

If it's still a problem after that then try creating your termbase in MultiTerm for the time being.  I'd also note that you should ensure this option is what you really want because the example templates for this often create a termbase for you that's full of unnecessary fields.  Most freelance translators only want, and need, and simple template for the source and target language with maybe a couple of additional fields if they have a use for them.  It's normally better to create the termbase based on your own definition.
