Glad to hear the problem is sorted. I don't have a answer why you weren't able to down load any thing before. What Anti-Virus are you using?
Did you upgrade with a clean install or from windows up dates. Is this the only problem you're having? If you can down load now, then I consider it fixed. If the problem returns we can try some thing different. I'm not a Chrome fan.
I prefer Firefox. You can down load it that and see if it gives you that problem. It never hurts to have another browser.
I have 4, but I prefer Firefox. Almost my bed time; but if you have more questions, I'll try to answer them! For another 30 minuites!
