Frontendusers login template forgot Your Password doesn't work

[cacharopnet]

I am using cmsmadesimple-1.7.1-base.tar.gz, but
both Forgot Your Password and Forgot Your Login Details don't work.

Forgot Your Password link to: index.php?mact=FrontEndUsers,cntnt01,default,0&cntnt01form=forgotpw&cntnt01returnto=80&cntnt01returnid=80
Forgot Your Login Details link to :index.php?mact=FrontEndUsers,cntnt01,default,0&cntnt01form=lostusername&cntnt01returnto=80&cntnt01returnid=80

Both just refresh the current page, doesn't load the corresponding template. Could anybody help me with it? Thanks a lot.

I was trying to create the group, and it gave me this error.
