Also note that Chris has been working on a fix for new GRIB file data formats and it may all come right tomorrow…
Go into the WXSim program folder and have a look at a file called custinit.txt, there should be some setup data in there but I've had it go blank on a couple of occasions. This leads to the error 62 issue
Budgie - you were so right - my custinit.txt file was empty but there was a .bak file there so i copied from that, so hopefully the next run will be ok.
