Update my OS using DM6.1

Windows 7 ; 32bit ; BB 9650 running OS 6.0.0.333 (old I know) ; DM 6.1

I have done a search but I don't think I used the correct phrase to find what I was looking for, or it's not there...most likely me though. :D

I downloaded the official OS 6.0.0.600 from CB and went through the install process on the computer ultimatley resulting in a prompt to open DM...so I did, so far nothing new to me. Went to the update item in the menu and it began a search for updates....nothing.

I remember the old DM being a lot more user friendly when it came to installing updates...honestly though I have been out of the loop for over a year now when it comes to updating. Any tips or links to point me in the right direction would be greatly appreciated

Thanks,
