Widgets started showing wrong data

Hi
I have using the GD-Listings on my website and all was fine. However I checked today and it has started showing incorrect data. Firstly one of the widgets stopped showing data altogether. It should be showing the upcoming featured events but it is showing nothing now. I also had one showing upcoming events and this now shows my things to do, not my events. I have tried adding a new widget but this shows old events. I have had to temporarily take my site offline as these are now incorrect. I’ve not changed any settings and all was working fine 5 days ago. I need two widgets – One to show my upcoming featured events and one to show my next 4 normal upcoming events. Can you help?
