WebmasterWorld members are reporting strangeness when using the Google AdWords Editor to retrieve statistics. According to some, the editor tool is pulling information, but "not all of it."
Google is aware of the problem according to the user. At this point, however, there is no solution and users report that they are still having difficulty getting all the data.
In the meantime, the suggestion is to use the online interface rather than the Google AdWords Editor. Forum members also believe that using the online interface is just better. netmeg puts it nicely:
I don't use the AdWords Editor for stats anymore; too often it doesn't match the online console. I've been given various reasons by Google as to why this might be (connecting to different servers that aren't completely in sync, console can see today's numbers while the AE can't, I'm making it up, etc etc) but the bottom line is, if I need to get stats, I have to log in.
