Why am I getting this error when I only created one data model since purchase?

my account plan says the following: 

Academic (Student)

Single user

Up to 20 models

Up to 100 tables per model

I am nowhere near those model and table limits but, when I try to spawn new tables I get the following error: 

"You have used 0 tables from your 100-table limit To create larger models, please sign up and then upgrade you account plan"

I talked to my database instructor and she seemed to imply I'm the only one in the class experiencing this issue and told me it must be on vertabelo's end and that I should ask them.. 

2а часа я ресовал структуру бд, в не зареганном состоянии, решил зарегаться, всё сделал по феншую, в отдельной вкладке, проверил то-же в отдельной вкладке, Но увы, после перехода на исходную ВАШ высер мне сообщил... УУУпс я всё слил в унитаз 2а часа работы в унитаз, ну как-то так !!! Вы бы блядь хотябы в локалстораж положили json объект с моделью БД что бы его можно было бы хотябы так выдать и воссоздать. Вы ребята совсем ёбнутые, спасибо вам огромное!!!

I have a 1:n relationship between Tenant table and Settings table.

In the relationship properties I setup a cascading delete property:

The generated SQL creates the constraint on Tenant instead of Settings.

My logical database option is disabled.  How do I enable?

I suggest creating a button to force update the data type of an FK field from its PK.
Or a PK-FK audit button, where it would be possible to check the tables that had the PK and its data type and all its dependencies, ticking which ones you want to force uptade.

I would be a great enhancement to be able to search all ERD we have access to for a table/view/column name and description, to return a list of matching description/name with a pointer to table/view.

we split our data across several models, database engines etc. It would help our team to locate information more easily.

currently, extracting xml of each model , consolidating data and serving to users to search through this list. would be great if this function were directly available on vertabelo.

My professor said that out accounts should be free on Vertabelo through temple University, but the site says that my account has expired for some reason. 

Any idea how to pass VERTABELO_API_TOKEN via Invoke-WebRequest in powershell ?

I cannot pass a credential with an empty pass, fails because pass cannot be empty.

I cannot pass my user/password instead,"no permission" message from website.

tried to pass it as POST ?VERTABELO_API_TOKEN=xxx, fails too.
