I’m having the same issue. I’ve also got a wordpress install using wamp on a windows xp pro machine.
When I set the permalink structure to default, everything works fine. It’s only when I try to customize the permalink that I have trouble. I checked my .htaccess file and it is being rewritten to. I also uncommented the line, “LoadModule rewrite_module modules/mod_rewrite.so” in my httpd.conf file… no luck.
If someone can offer some assistance it will surely be appreciated.
