Replying to Premier Pro Sequence Settings Missing

So my sequence settings disappeared which include DSLR etc. I believe it is because something went wrong and Adobe realized and put me back into the trial which expired.I have tried uninstalling and reinstalling with the patch, but adobe still asks me for a serial.

So I think I need to make a new adobe account, with a new trial. I guess my question is- How can i put in a new account, so when it asks me after installation whether I want to licence or trial, it doesn't use the expired account.

Any other suggestions appreciated.

Thanks!
