I have just purchased a premium account and I'm not sure if I can use the same username and password as I have for mobilism.

Yup, you can.

I tried to download using my mobilism log in and it wouldn’t accept it. So I requested a change of password for premium account and I have yet to receive an email advising new password. I have checked by junk folder as well but there is no email.

I'm still waiting for an email with password change, so I haven't been able to access premium.
Please check your PMs. For future reference you should always PM me here rather than use the firstname.lastname@example.org email, you'll get a much faster response and the request will always reach me.
