this is the error message.
and it recommends me:
"If you have a real proxy, make sure it is configured to allow port 80 .NET remoting traffic. If you do not have a proxy, you may have leftover problems from malware in which case you will have to disable the proxy on your machine."
I have no proxy and malwarebyte doesn't find any malware
I know this is an old thread but I came across someone with the same issue. What worked for them (and I dont know why, but it did) was they went into their internet settings>connections>lan settings the box for proxy was not checked as it should be, the checked it then unchecked it and after that it worked, not sure if the hit apply after checking it and then again after unchecking it but if you still read this try giving that a shot.
