Hi
Had some stability problems with CS5 Premiere that I had to install twice. Now I have uninstalled CS5 and want to install again. BUT my system again have problems with the installing of my DVD's. Can I install the tryout with my serial numbers from the DVD and will it work in the same way, as the DVD version ?

Have you run the Abode CS5 clean-up script.

It cleans your system of all trace of CS5 products which usually solves installation.

If not, follow this link, Adobe - Adobe CS5 Clean Script (http://www.adobe.com/support/contact/cs5clean.html)

Its worth a shot.
