Your build number (39561) does not match any updates there are for 2009, only 38599,39979-40040 are available. Seeing as your build number is mid way between the 2 patches I think you may have SP 1 but by a different distributor.(not Auran)
Just checked the build list - you appear to have the Spanish retail version, which does not have an easy patch route - you will need to look for a patch to take you to 40895.
