Hello stoney69, unfortunately I do not have the VP ModPack anymore so you might be better placed putting this error to the thread from where the mod pack is available, Istvan did re-paint the map at one time and he might have altered the set up for the map in some way for his pack.
You could download the map again from the link I originally provided (does it still work?) and add it into the VP Modpack as you would any other, from there I might be able to replicate the issue you have and help from there with a new install.
Not sure what you mean here: "Land scape error", sometimes folks get a 2D error, I forget exactly how it reads but if it is that look through the thread and see if it came up before for anyone else.
You mention "JetWar. Log", there are two versions of the map, any jet based pack will most likely have the 1967 version, not sure with VP ModPack if you would need to load that if using the jet add on.

Wishing you all the very best, Pete.
