ANTI-SPLOG and MEMBERSHIP 2 PRO

ANTI-SPLOG and MEMBERSHIP 2 PRO these two plugin should work well together, correct?
What would cause the Renaming of wp-signup.php
to http://excelcoupons.com/signup-091/ not to work? If you try this link it wont work because I have it password protected. I want to know if these two plugins work well together and I should have not problems. Right now on my end when I click on the new link above its a blank page.

Checking this option will disable the wp-signup.php form and change the signup url automatically every 24 hours. should it work automatically?
