Just bought Cingular Treo 750 and tried to load Slingplayer Mobile PPC and no go! Upon syncing, the file appears to download. I get a message on desktop PC saying program being installed and to check my mobile device screen to see if additional steps are necessary. However, nothing appears on my Treo 750. It doesn't show that the player has loaded, doesn't ask me if I want it on storage card or the Treo's internal memory. Anyone know what I'm doing wrong? I've loaded other software on the device with no problems, so I don't think it's the phone, itself. Appreciate any suggestions to try.
