I upgraded IE on my PC about 2 or 3 weeks ago since I kept getting error messages and IE would lock up. I had to download and install it at least 3 times for it to work.I have Windows 7. For the past few days I am unable to open or send messages from my Hotmail account if using IE. I can do both if I use Chrome on my PC and I can do both from my iPhone and iPad. I don't like Chrome and I can do more things in Hotmail on my PC. What can I do to fix my Hotmail?
