Scheduling Apex Class Error

Hello,
We have been using the same apex class since 2014 to create a new batch of Opportunities at the beginning of every month, so that we always have a set of 11 Opportunity forecasts. However, for the first time I'm receving the following Error: You must select an Apex class that implements the Schedulable interface.

Salesforce support cannot help without a Premier package, so I'd really appreciate any help on the matter. Please let me know if you require any further information. 

Thanks!
