Database error when filling out a poll as anonymous

I'm getting this error too. Any ideas on it? pollfield works perfectly for us, otherwise. Fixing this would allow us to use it.

Thanks!

I am at beginner level with php, but I was mucking around with the module and I made some changes that will allow anon voters to vote without that error showing up (i have new error, but they can still vote).

Here are the changes I made to pollfield.module:
(although I don't know how to write patches yet, I'm trying to give the changes in 'patch style' (with layman comments following, lol) )

layman's explanation:

hostename should be hostname
':table'=>$table, should be ':table'=>$vote->table,
'hostname:'=>$vote->hostname, should be ':hostname'=>$vote->hostname,
$query on line 637 repeated
in the function pollfield_save_vote_record the ifs for IP & cookie were left out

I am getting this error, although the voting still happens

Strict warning: Creating default object from empty value in pollfield_vote() (line xxx of [...]\sites\all\modules\pollfield\pollfield.module).

one other change i left out...

There is an extra apostrophe right before AND field_name_delta=:field_name_delta",

I am getting the same error, as this fixed then?
