Do you have a .pub file of the public part of your identity?  try
pointing Identities to that file.

if you don't have such a file, you should be able to do:

   ssh-add -L

filter the output to the line you want, save the filtered output to a
file named "foo.pub" and then try with "ssh -i foo.pub remotehost"

hth,
