Troubles, troubles...So today I couldn't even run the updated 6.0.5 WL PC program due to some dll files missing... bummer!
Called Davis and support was good but the only way they could suggest to get it going was to install the full version 6.0.5. Reluctantly I did, and that went ok, copied in my data folder and templates and back to running... but still the same error.
Called Davis again, and a different support person (Bruce who was most helpful and knowledgeable). He used TV and said he had never seen that error before. He went thorough some station settings and then in the internet settings and after a bit of looking ticked Use passive mode... and next 5-min update the error disappeared, all set again. Good support experience again.
Enjoy,
Paul
