We didn't store that level of information. Sorry...

According to stackoverflow.com posts, they recommend removing

C:\ProgramData\Oracle\Java\javapath;

Does that file exist in the SAVE folder?

It looks like the database lock file may not have been cleaned up since the last run.

But it's odd, since I don't see any of the trackerdb files, which is the database.

witptracker.properties file.

Is that where the file is located? The error message indicates that the save file couldn't be opened for some reason.

You need a later version of Java JRE (like version 8).

Larry: there is another panel that has all of the mine information. I suppose I could also display it in the base panel...

Copy all of the trackerdb files (five of them when the program isn't running, I believe) to the laptop and it will pick up where you left off on the desktop. Then do the opposite when you're back. All of the per-game data is in those files, so that's what you need to move around.

It's in the code that loads the operations.txt file. Could be a bad character or some other parsing error. You may be able to just ignore it.

I am a little ashamed to say that Floyd has held up the Fort without me for years. He deserves all the credit for remaining active and answering all your questions. But if he ever needs me to spaghettify the code some more, I stand ready to dive back in and screw it up some more. Take it easy, fell...

It looks like these "can't find device" warnings are related to convoy reinforcements that have aircraft in them. I'd need to fix that somehow.
And the group withdrawal alerts are also misguided and I need to look into that.

Agreed that both are annoying.

Glad you got the right JRE, Larry.

Larry - What version of Java JRE do you have? From the DOS prompt, type "java -version" (without the quotes). Mine looks like this: C:\Users\fgold>java -version java version "1.8.0_371" Java(TM) SE Runtime Environment (build 1.8.0_371-b11) Java HotSpot(TM) Client VM (build 25.371...

Perhaps the database files are corrupted. At least from the code, the error is coming from when the database file is first opened (and before anything is read).

Make sure the file is where you set in the witptracker.properties file.
You could also use the multi-read turn function and manually navigate to the file location.

It could also be the turn of the save file. If the turn is not a finalized turn (End Turn used), that could be the cause.

- it shows sunk ships sooner than the in-game tally :-) especially ones that sunk on the day but they are not shown yet (no idea what sort of magic does it use to do so). Helpful if you need to decide if you should pursue a wounded enemy. Well, it's not supposed to do that... I'd like to fix that i...

You need the JRE. The latest should be JRE8 Build 371.

The result should look like this:

This is typically a JRE version issue - what version of the JRE are you running? You need at least 1.7 or 1.8.

From the DOS command prompt, type "java -version" to see the version number.
