backer dvd updates?

[war3069mission]

hello...

 

i bought a copy of a backer dvd in flagstaff,AZ. i was just wondering where/if i can still do updates. i have this link and i am updated to 2.03. 

 

http://eternity.obsidian.net/downloads/patches

 

but as the patches on that page only go to the 2.03 and your now on 3.02, i am losing out (i think) on all the updates since 2.03.

 

not a biggie if i have to re-purchase the game thru gog or steam... just i will have thrown away $20 on that backer dvd....

 

this game is totally awesome and i cant thank you enough for making it happen as this is my style of gaming...

 

thanks in advance for any info on my little issue
