so i got a captivate on friday and ive been messing with it all weekend, i like it! but i can not get it to connect to my pc? i searched this site for hours and tried countless things but nothing worked? im running 7 ultimate 64.. ive tried plugging into the front and back usb ports, installed the drivers for 64 bit, over and over... when im plugged into the back usb it doesnt even show up in my computer, but i can see it in the device manager as a usb device, with an error. when plugged into the front it shows up as a removable disc, or 2.. but its lags really bad and freezes up if i try to open it, i/o error. but it has worked twice? kies has been a disaster! its never worked and usually crashes? never has it seen my phone, ive tried every setting the phone offers. even formatted both sd cards.. anything im missing? sure would be nice to have this simple thing work... never had this problem?
