Hello Jose,
The first error ('The database that you added is not a valid BigFix database') is pretty clear.
You've filled in ILMT database name (temadb) in place of Bigfix Server database (BFEnterprise).
The second error ('The data source that you added is not subscribed to the IBM License Reporting fixlet site...') means unfinished BigFix installation procedure.
If you open up the BigFix Console do you see any sites under 'Sites -> External Sites' ?
Upon successful installation you should see 'IBM License Reporting (ILMT) v9' entry...
Does your BigFix server deployment has the Internet access or not ?
Have you enabled the fixlet site: 'BigFix Management -> License Overview -> IBM License Metric Tool' ?
Please make sure to conduct all the installation steps:
