Nothing working on this plugin anymore

Hi there, nothing is working within this plugin anymore. All of a sudden all my settings have just gone. It took me ages to manually input all the payment methods for over 100 curreecies. Now they are all gone. None of this works:

1. In the location tab Selecting ‘get country by currency’ doesn’t work
2. In the location tab Inputting the country in manually and then selecting ‘save’ doesn’t save anything
3. In the checkout tab selecting ‘change all checkout status to yes’ does not save
4. Manually adding payment methods does not save on any currency
5. Adding my auto update key does not save and does not work

The WHOLE PLUGIN is not working anymore!
