I have been lurking on this forum for the two months that I have had my Captivate. I first want to first thank the many people on this and the XDA fora who have helped me root my phone and install too many apps for my own good. One of my goals is to use Kies to sync my Captivate with Outlook on my desktop (no exchange server, no download via Google). Kies 188.8.131.5293_82 installed on both my Vista laptop and my Windows 7 laptop recognizes my Captivate with no trouble. I have been unable to make it work on either of my XP desktops. Now to the issue. Last night, on opening Kies on my Windows 7 laptop, the program suggested that an upgrade was available. I installed version 184.108.40.20603_100. Kies would no longer recognize the Captivate. I rebooted everything, reinstalled the drivers, then rebooted again. Still no joy. I deleted the new version, ran CCleaner to clear the registry and reinstalled _82. All is well again, I think.
