usb driver help!

[scdjack]

I have a captivate and had kies (Korean) installed on my computer. Everything worked fine for six months then kies quit working. I uninstalled Kies Korean and installed kies mini, and usb drivers, now when i connect my captivate to pc to try to connect to kies mini i get a dialouge box saying installing drivers, then drivers not installed properly. when i check my device in DM it says a mtp driver is installed and will not update to anything else even when i try to poing it to the correct samsung driver file. Trying to use AC sideloader device wont show up when sideloading app. Please help me I've searched everywhere, talked to Samsung(what a bunch of ****s), uninstalled everything and reinstalled. TIA
