i downloaded an update from creative suite 5.5. to 6.0 and then switched computers for a few months. looks like all of the applications have not disappeared. maybe a trial was uploaded instead of the actual updates? anyway, i just want to get the app

there is no update from 5.5. to 6.0.

you could have upgraded from 5.5 to 6.0, but you would know that because you paid money.

assuming you paid no money for a 6.0 upgrade, you still have your 5.5 license.  uninstall clean and reinstall 5.5 per http://helpx.adobe.com/creative-suite/kb/cs5-cleaner-tool-installation-problems.html
