lo pego directamente.. al hacerlo ya me detecta las mesas el table manager el solito y me sale el hud.

Please configure your hero names under hud options -> setup hero names.

But i think something went wrong when you used table finder the first time:
please close HM and rename the file exenames.txt in the config subfolder of your holdemmanager installation path.
Restart HM and a new file will be generated. Open a betfair table and let the autoimport run and import the hands.
Now use the table finder again and drag the red cross for the unattached table onto the middle of the table. Close the table manager with the OK button, a message about the modification of the file exenames.txt should come up and it should work from now on.

If that doesn't work please schedule a remote support session with our support. Email support@holdemmanager.net, with a link to this thread and your forum name, so we can setup a Teamviewer session.
