+ AA6YQ comments below
I have been off the air for quite a while putting up a new tower and antenna.
Today opened DXLab to update what I have missed. I'm told "Unable to open LOTW database Unrecognized Database Format C:\dxlab\dxview\databases\LOTW.mdb".
Sounds like something happened while OTA.
+ No DXLab application attempts to modify the LoTW database; with respect to this database, they are all "read only".
+ So I can see what happened to your LoTW database, please place the file
+ in a zip archive, attach the archive to an email message, and send the message to me via
aa6yq (at) ambersoft.com
+ Then do the following:
1. terminate DXView, DXKeeper, and SpotCollector
2. delete the file
3. on the Databases tab of DXView's Configuration window, direct DXView to install the LotW database
