Problems with Cubase Le4

Hello colleagues. I have a problem with my Le4.The program is fully registered, but i still have problems always when i make records - its not possible to correct nothing in audio channels. Drivers setup is OK, sound is perfect, but I cant do normalizing, EQ, and etc. Can you help me?

Maybe worth deleting the preference files

I try this steps, but withowt any efect. Sounds is nice, but not possible to do anything.

Bit short on the detail. It may help to provide some insight as to what you are doing and how you are going about it?

maybe some screenshots along with a better description of the problem/s and system spec, O/S, soundcard, etc.

Thanks. My problem was in drivers. After removing Realtek HD drivers\chip set is Intel\, program works wonderfull. Thanks again.
