Unable to access the data

Hi, I have been invited to join a group for the business I work for. At first, everything was fine, I had access to everything. However, a few weeks later, I can still login and my account still appears as active in the admin's panel, but the CRM shows me an empty database. Basically, I can't access any activity/data from my account.

I tried deactivating and reactivating my account via an admin's panel, but it still gives me an empty database...
