Single Validation Key

I purchased the ChronoForms 1 key but when I go to validate on my site that option is not in the drop-down box. There is only:
3 keys
5 keys
chronoforms ultimate
PayPal
Authorize.net
2checkout
What should I select?[h4][/h4]

Dunno, pick one and try it? If it doesn't work nothing's going to happen.

Hi vipcca,
​
Please check that you have the latest release of CFv5 installed - Max may have updated the options??
