I just deleted (via AppCleaner) my Mac App Store app (which I couldn't log into for 2 weeks) with the idea to re-get a fresh app via Software Update.

But Software Update doesn't download Mac App Store anymore.

How can I re-install Mac App Store on my Mac? Thank you.

Use your Time Machine backup to get it back. –  Thilo Mar 9 '11 at 10:12

There isn't a stand-alone Mac App Store updater. Your best bet is to reinstall Mac OS X 10.6.6, using the combo update. It's a 1.06 GB download, but it contains all the parts of prior updates (the 10.6.1, 10.6.2, 10.6.3, 10.6.4 and 10.6.5 updates) and should repair your current install.

BTW, that my erasing of app didn't help with signing in. But this answer did: apple.stackexchange.com/questions/7459/… –  user4261 Mar 9 '11 at 12:11
    
@Boris: Thanks for letting me know. I'd thought that you had a two-part problem, but I figured that it was best for future questioners if I just answered the actual question you asked. –  Negrino Mar 9 '11 at 19:01
