iCodes Plugin

I just installed a new copy of CouponPress Responsive and the iCodes plugin 1.8

I have tried almost 20 times to get this to work. When I import the merchant list, it runs for a little while (about a minute) and then gives a 404 error. It imports some of the merchants but I need to run it again to import more. I have done this so many times but never get to the part where I import the actual coupons; it 404’s me everytime after 50-60 seconds.

Any ideas?

I have a paid icodes account.

Thanks,
Tim
