I'm not familiar with this module, but in general you can catch calls to die by wrapping the fatal code with eval. Your code will look something like this:

eval { $t->login(Name => $login_att[11], Password =>$login_att[12]); 1 } or warn "Can't Login: " . $t->errmsg;

In the general case, $@ has the error you would normally get printed on stderr when the script died.
