We can't know. Settings not being stored or loaded usualyl comes down to file permissions and user privileges issues. for anything else we would need much more info and a better explanation what the problem actually is.
thanks for your answer. i will do my very best to discribe in english what my problem is.
I saved my ps-settings before installing a new harddisc on my computer. PS CS5.1. is running. But the setting are gone / the software doesn`t use it, althought i used the same folder for the settings on the new harddisc. Especially the actions are important for my work.
I am the only user on this computer, so there should be no problem about permissions.
