Okay, so yesterday, my Skype totally flipped out and shut down (I'm using 5.10, remember). For the life of me, I could not get back in (it kept showing the irritating "Skype could not connect" error whenever I typed my password in). I uninstalled 5.10 and reinstalled it, but to no avail.
So, the first thing I did after that was run over to Services to check on the skype updater. To my horror, it was NOT disabled, like I had done to it over a month ago. I redisabled it, and tried 5.10 again. It still didn't work.
I removed Skype Click to Call (which was running version 6.21 for some reason). Still didn't make my Skype work.
Scratching my head at this point, I removed Skype from my computer and downloaded version 6.21. This time, it opened up without a problem. Irritated still, since I don't like ANY of the new features, I decided to try once more to reverse the problem.
I checked in the Temp folder (C:\Users\<your_username>\AppData\Local\Temp) and found that 5.10 was still the SkypeSetup.exe there, so I went and uninstalled 6.21, then reinstalled 5.10 from the exe.
To my surprise, Skype opened up with no problem this time.
So, I guess I would write out this procedure like so:
1. Check to make sure the Skype Updater is disabled in your services.
2. Remove Skype Click to Call
3. Remove your version of Skype
4. Download a more recent version of Skype, sign in.
5. Sign out, delete the recent version of Skype.
6. Redownload your version of Skype.
7. Hopefully, bask in victory.
I hope I don't have to repeat this process every time I log out of Skype or it crashes, but I will if it means getting to keep my 5.10!
Happy debugging, everybody!
