More information is needed about your installation:
- What is the operating system of your SEPM?
- Which version of the SEPM is installed?
I don't speak Spanish, but it looks like the most recent message pertains to Rapid Release definitions... what exactly is the message reflecting? That they can't be installed?
The other one you circled looks like "Unexpected server error"... not much I can find on that besides making sure it's on a server OS and not XP.
One of the other messages looks like LiveUpdate can't run because it's already running. Under Site Properties ("Editar propriedades del sitio"), then the LiveUpdate tab, how frequently is LiveUpdate set to run?
