buddies icons not showing

[Pro-DT]

had problems with old Pidgin - couldn't connect anymore to messenger, so I upgraded to last version of Pidgin (2.5.7)

the problem is that Pidgin does not download buddy icons anymore (cheched in Documents&Setting/.../Application Datas/purple/icons = folder empty) and doesn't show any icons as avatars (normal, if it cannot get them from messenger server).

what is it to do ?

i am connected without any proxy.
