Fieldset issue with recent Gravity Forms updates

Specifically the address field, the str_replace to add the open fieldset tag seems to have changed from the string you are looking for. I was able to get it to work by editing line 263 and replacing with:

<label class='gfield_label gfield_label_before_complex' >{$field_label}<span class='gfield_required'>*</span></label>

Without this opening fieldset replacement, the plugin adds an </fieldset> tag without an opening tag which throws HTML errors.
