There has been a bug in both AdWords and Sklik extractors which caused undelivery of data to input tables since Feb 17 13:00 UTC. Actually the data had been saved to wrong bucket: in.c-ex-adwords instead of in.c-ex-adwords-[config] (similarly for Sklik). You can get the data there if you have only one configuration for the extractor. Otherwise data for more configurations will be mixed in this one bucket and so it will be safer to run the extractions again. Now the problem is fixed and should not occur again. We are sorry for any inconvenience.
