I don't know.
I hope I solved this problem.
You use the restriction "OrderTotal". Old release of the plugin doesn't know what nop order we need to take.
This new release will take the order with the biggest amount.
1. Upgrade pluginhttp://www.foxnetsoft.com/content/files/FoxNetSoft.SmartCampaigns.zip
Replace all files from the new ZIP file and restart nopcommerce. Plugin will upgrade itself itself.
2. Plugin uses the nopcommerce task manager.
Maybe you use sandbox and store's URL is not leave. Nopcommerce runs tasks itself.
Check the list of stores in nop admin mode. Do you use the correct store URL?
