If its CS6 download again.
It's not quite explanatory enough. What version? Are you missing any Presets? Try this:
- Uninstall CSEverything from your system.
- Regardless of your version, run Adobe - Adobe CS5 Clean Script
- Run the clean script again.
EDIT: Or just do what Ann said.
damn that was fast answer thanks, ummm ist CS5, is reinstall really the only option?
If there are no presets it means its turned to trial version.
Just do what Jeff said.
You can just try by de-activating it and reactivating Premiere pro.
OP is on CS5, does this trick also apply to CS6?
