Preparing a trip to Spain, I found some errors in the location of certain ULM fields, as well as others missing. I created/corrected using the Custom Data utility (great thing). When I try to attach the files, my web navigator crashes, so I will send de XML files by mail to Tim. I checked the new locations using the "view on map" facility.

Unfortunately we cannot simply replace our data with data sent to us by a customer. Can you instead simply let us know which airfields you believe are incorrect and in what way? Then we can ask the person responsible to investigate.
