First of all... www.RvSGaming.com and www.CrKrS.com use the PHP Engine code. 

Websites that are made with PHP are cookie based. 

Why are they cookie based? Because once you log into site you change the preferences and the outlook of site to suit your needs.  The site then places a "cookie" on your computer so the next time you come back to the site and log in, your prefernces will still be the same.

Okay now knowing that.  

• Open up your Internet Explorer and on the top click on Tools option.  

• Go down to Internet Options.  

• You will now see a variety of tabs along the top. Click on the tab that says Privacy.  

• You should now see a slider bar.  If that slider bar is set too high then that is why you can't log in. 

• Turn that slider bar down, apply the changes, restart browser, and try logging in to www.RvSGaming.com or www.CrKrS.com again.  

• If this still does not work please contact me or leave a message in our forums.
