NBA 2K9 iff Editor problem...

can anyone help me.. my problem is when i save texture as png. then i drag it to photoshop CS7 then edit it., then i save it to png. then when i drag it to iff editor nothing happens... anyone know how to solve my problem... im using windows 7...

is it 32 bit or 64 bit?

64 bit..

There are known issues with the editor on 64 bit. I have 32 bit Windows 7 so I have no prolems.
I dont think there is a solution to this problem at the minute, anyone using the IFF Editor with 64 bit?

can i change my pc on 32 bit??
