I can't update some Apps I bought from the Mac App Store. I bought these apps before updating to the last 10.7.5 but I am not sure when this problem started happening as I was not getting any messages for updating anything for a long time, which made me suspicious and check with certain Apps like Pixelmator what their last version was, and that is How I found in the "Purchased" apps section that there were plenty of them with the Tag "Update". When I try to do so, I get this message " You have updates available for other accounts. To update this application, sign in to the account you used to purchase it. " , which is impossible because I do only have one Apple ID account that I used to buy all my apps with. Does anyone know how to solve this? I tried deleting the apps, login out and in again to the MAS, but nothing seems to work. Not sure whether this may be related to the problem or not but I am also having a problem with repairing Disk permissions, it shows lots of them, says they have been repaired, but on any subsequent run of the Disk Utility, it shows over and over again the same permissions as not being repaired, and re-repaired again, apparently the Disk Utility is actually doing nothing! Any inputs or Help about this? Thank you!
