Simple map blocking my own IP

I’m trying to use simplemap to show the locations of various stores in one map and have them be selectable (click the store name, map zooms to that location).

It looks like a great plugin, but when I try to activate it, I can no longer access the site/host/ftp from my computer (other computers have no trouble). The hosting provider said there was something coming from the functions.js.php file that the host interpreted as trying to hack the site.

This is what they sent from the hosting provider:

[Thu Mar 18 14:19:01 2010] [error] [client 24.136.14.132] ModSecurity: Access denied with code 406 (phase 2). Pattern match “\\%(?![0-9a-fA-F]{2}|u[0-9a-fA-F]{4})” at ARGS:map_width. [file “/usr/local/apache/conf/modsec2.user.conf”] [line “32”] [id “950107”] [msg “URL Encoding Abuse Attack Attempt”] [severity “WARNING”] [hostname “myrura.com”] [uri “/wordpress/wp-content/plugins/simplemap/js/functions.js.php”] [unique_id “S6JulUU5qMIAAAg0ai0AAABW”]

does anyone know how to fix this? This seems to be the only customizable map plugin that does what I need it to, if anyone has any other map plugin suggestions, please share
