I am not a user of ac but that error is indicative of not enough storage space. be it total hard drive space or declared database space..
Not knowing the specs of the server you use, Or what changes happened prior to the error.
If you google
2147217900 (80040e14)
You will find a Microsoft update may be required and a method to open up declared database storage space.
Also Compatibility Level of the Database may need to change
If it is hard drive space then you would need to add disk storage.
The second paragraph also can be googled and will tell you basically the same.
You can google portions of the error text or all like just PRIMARY filegroup is full.
If in a rush then the most probable fix is to find something you can purge out of the database.
That is my 2 cents take it for what it is worth.
