Can't login - Please help

Hello.
I have been using Soulseek for years, but first time I have this problem.

I had the username "Volmineux" for years. But last week, I could not login for a week. I downloaded the last Slsk version but nothing helped.

At first when I was connecting, nothing was happening (no message) but the soulseek bird was remaining in brown colour (sometimes it was turning blue but not for long and I could not enter a room for instance).

So I decided this morning, to create another login, now my username is "Cha Er Fang".

I then launched Soulseek and to my good surprise, I was connected, could enter rooms, and could see other users online (in my user list), I even could browse user's files.

Unfortunately it was only possible 5 minutes.

Now, again same problem. Can't login, and now I have this message:

Login failed. Reported failure reason: socket error. Please change your login settings in the Options tab and try reconnecting.

Anyone willing to help? Would really appreciate it. Thank you in advance.
