my d2 disk is pretty much fucked so i dl'd it from blizz but i cant get it to work. question is did i hav to uninstall b4 i download it or can i do it now? does it matter? thx for help.

No just put the new blizz dl one in a diffrent place on your pc i.e dont name it default ''diablo 2'' or w/e

If you already had it installed all you need is the MPQ files in the D2 folder. (only 2 of them I believe)
Then It should work without a disk

where do i add the 2 mpq files too? somewhere in the d2 program files i assume but where exactly.
