Trouble installing AIM

i opened AIM today to sign in and after i signed in there was a pop up saying there is a new version of AIM and asked if i want to upgrade it,i clicked yes
after downloading the new version it doesnt work
it installs fine but when i sign in it stays in the connecting part of sign in
i uninstalled it and installed the previous version of it and then this one does the same too
it was working fine today until it asked for upgrade
anyone know of how to fix it?
have you have this problem?
