cimy user extra fields uninstall problem

I installed cimy user extra fields but couldn’t get it working so have deleted it but now I can’t access my registration page because of this error:

Warning: require_once(/hermes/waloraweb006/b1208/moo.perfectcandidatejobs/wp-content/plugins/cimy-user-extra-fields/cimy_user_extra_fields.php) [function.require-once]: failed to open stream: No such file or directory in /hermes/waloraweb006/b1208/moo.perfectcandidatejobs/wp-content/mu-plugins/cimy_uef_mu_activation.php on line 31

Fatal error: require_once() [function.require]: Failed opening required ‘/hermes/waloraweb006/b1208/moo.perfectcandidatejobs/wp-content/plugins/cimy-user-extra-fields/cimy_user_extra_fields.php’ (include_path=’.:/usr/local/lib/php-5.2.17/lib/php’) in /hermes/waloraweb006/b1208/moo.perfectcandidatejobs/wp-content/mu-plugins/cimy_uef_mu_activation.php on line 31

Any ideas as to how I can sort this out.
Thanks in advance
Mitch.
