In the M-Files Admin app, I am unable to run any processes. How do I fix this?

My company has a trial version of the MFiles Cloud application. There is only one user currently, me, and I have admin permissions.

We are currently testing the admin features and are having some troubles.

For instance, when I try to backup a vault, I am given the error "You do not have the access rights required by this operation".

Is there a configuration issue that I need to resolve, or is it that we only have the trial version right now and can't perform these operations in the trial?

We would like to test these features.

Thanks in advance.
