thx for your reply CyberSpatium, ive searched for mod_rewrite in the httpd.conf en uncommented this line ;
AddModule mod_rewrite.c
there were just 2 lines with "mod_rewrite, the other one was this;
LoadModule rewrite_module modules/mod_rewrite.so
when I look at the site now it doesnt give me an Internal Server Error anymore, but when I click on the link thats shown in the default wamp index it gives me a Bad Request, when i put a slash behind the url its okay.
however i would like to make use of "fancy urls" made by htaccess on my local host. these work on my payed host, but not local....
HELP !!
