If you are getting a "License Invalid" error on the login page of Pinnacle Cart, yet you are 100% sure the hostname and license key are valid, then apply the fix below:
- Download the attached zip file and extract it
- Read the readme.txt file
- Notice there are two folders, one for zend and one for ioncube
- Upload the contents of either the zend or the ioncube folder to the cart root, replacing the existing files
- After doing so the login issue should be resolved
