Did you uninstall CS4 after or before you installed CS5.5?
Were these custom presets, or standards ones that normally are installed with the application? Unless you have backups someplace, your custom presets are most likely gone unless you left them in your library.
Thanks for the response.
I uninstalled CS4 after installing CS5.5 (I later learned that it would have probably been best to just install CS5.5 [without ever installing CS4] and use my CS4 registration # to install CS5.5.. I called Adobe Tech. Support to get advice and direction and they are the ones that told me I should have not problem and thus I uninstalled CS4).
I didn't have any custom presets...so, I'm just looking to install/regain the standard PDF print presets that should be loaded each time I launch InDesign.
Uninstalling an old version after installing a new on can casue all sorts of odd problems. You need to uninstall CS5.5 and reinstall, but frankly, I'd put CS4 back in first.
