Checkout page doesn't load when purchasing a gift certificate

[tk42one]

Hi all,

Bit of a problem here, I just tried enabling Gift Certificates on my site and everything seems fine except when you proceed to checkout with a GC, then you are greeted with a completely null page and sometimes a "too many redirects" error. Attached are screen caps of my GC product, the attributes and the GC orders module. Anybody know where I went wrong?

NOTE: I've tried disabling FEC and changing back to the default template but I always get the same results.
