I have had this problem for over a month now. I can log in from other computers but not from my own. I haven't had the chance to test another account on this pc. I'm not at any university campus or such.
One day my spotify just stopped letting me in, showing the 101 message.
Sometimes it'd let me in but claim that I'm in offline mode.
After googling about the problem I tried to access my antivirus (at that time panda cloud) but it was somehow broken and couldn't open. I uninstalled and reinstalled the antivirus and spotify both multiple times but neither would work. At some point I tried to find out if I'm using a proxy server but it seems I'm not - I tried all kinds of proxy/ip revealer sites but they always said "no proxy server" or "no information available".
So naturally I go ape**bleep** on my computer and scan it with three different antivirus softwares and spyware softwares also.. I did not install antiviruses on top of each other but did each scan separately. There were mostly spyware and a trojan somewhere but they got fixed.
My nerdy friend told me to also reinstall Microsoft's .NET Framework thingy just in case, so I did that also.
I ditched panda and left a free trial of avast! installed on my computer. However, the problem with spotify has been around no matter what antivirus and/or firewall software I've had installed. Even when I had absolutely none of any antivirus or firewall softwares installed (just windows firewall, with spotify allowed) it didn't let me in.
Additional information: Before running the virus scans I had problems with all sorts of online installators - java and panda for example. So I was absolutely sure the problem was because of some virus that messed up the connections or something.. but after fixing all the other problems the most important one still doesn't work - spotify!
So what more can I do? I'm paying for unlimited now and I love the program but if I can't fix this, I'm ending my subscription this month. (How do I do that by the way?)
Thanks,
Elina
