Thanks Hubert, just sent the files via WeTransfer. The Campaign seemed to launch OK, and I could operate everything else as normal until I clicked on the "Purchase" tab. My last changes to the campaign after the last successful run, which may have caused/instigated the issue, was to change all the #DATE values in the script editor that were 9/1/1939 to match the start date of my campaign (4/28/1939). The premise was to use shortened production delays and large Initial MMP values to allow the countries to build their land/air forces from "scratch", and to give the German player the option to invade Poland anytime after June 30, 1939, but not necessarily invading/starting war automatically on 9/1/1939. The other thing I was doing in the Editor was to add/edit the lists of unit names, specifically German U-Boats, and it raised a couple questions:
1) is there a limit to the number of names in these lists?
2) how are the lists sorted? Most of them go alphanumeric, except the HQ's which seem to go by "Rating" then alpha?
3) Is there a way to specify/override the sort? It would be nice to arrange it so is would go 1st, 2nd,...9th, 10th instead of 1st, 10th, 2nd, 20th, etc.; and finally,
4) Is there a way to "import" a bulk list of names instead of having to type them in one at a time, perhaps using the Import/Export Data functions?
Update suggestion: in the editor, under Campaign / Edit Country Data / Edit Unit Build Data / Advanced window, could you add a button to "mass update" all the Minimum Production Dates en masse, like you can do for other unit build data? I found out the hard way, that when you change the start date to an earlier point in history, you have to change EVERY one of these values one at a time, for EVERY nation or you won't have them available...that probably consumed more time than any other part of my scenario building in this case. And there were a few that I missed updating, which I didn't catch until playing the game and wondering why certain units weren't available.
Sorry for the saturation bombing of questions, but I'm an old board gamer and I think this editor is THE BEST I've ever worked with for customizing games. I'm curious about the nuts & bolts of customization, I've been working on using the editor to create a scenario of the Battle of Jutland (WWI) and a Napoleonic (Battle of Eylau). I absolutely LOVE how in the editor you can limit the countries/units to just those you need, and how you can "customize" units just by tweaking their combat/data values. Well done!!
