I received an update notification last night for some apps. No biggie I thought, selected the notification and received a password request. My intial thought was that I had gotten hacked. Spent quite a while trying to key in any password I have ever used to no avail. Logged on to Gmail and You Tube on my desktop, changed both passwords and still couldn't get in. This morning I got a notification on the phone to enter my you tube password (I changed it last night). New password took ok. Great I thought, now I should be able to log onto the market. It seemed to take the password, but then I have to try (and I do mean try) to enter the cryptic captcha message (10 times or more). No go. I tried to wipe the application data, no go. Finally backed the Market updates down to the original version (that I'd never seen on my DX2) and was able to log in with no problem. That's about 90 minutes of my life I'll never get back. Have no idea what the heck happened there.
