530 error cannot log in

[Iguanagirl77]

I last used filezilla in Sept 2012 with no problems, now I cannot log in.

Error: Could not connect to server

I'm using windows 7 and the latest version of filezilla 3.7.3
My site is hosted with Mrsite
Ive tried my password in both upper and lowercase
my firewall is set to allow filezilla through although I have tied with my firewall turned off completely but that had no affect.
I have also tried shortening my user to fabuloso-splendido and fabuloso-splendido.c as Mr site says: If your website address is longer than 20 letters (e.g.myfirstwebsiteishere.com) then your FTP username will be the first 20 letters only (so, you would use myfirstwebsiteishere). The password is your original Mr Site activation code in UPPER case.

I have also tried switching between passive and active modes, with all variations of above and still no affect.

when using the config wizard this is the report

The server does accept your user credentials. Please call the support staff and ask for help there. This is NOT a problem with FileZilla as-is.

I of course meant: The server does NOT accept your user credentials.
