Problems with Japan 45 PBEM files

[Secret45]

Good evening,

I recently started a campaign (the regular Operation Olympic campaign) in Japan 45 and had two bigger issues with the BTE files. While one of the cases is a minor inconvinience the other one makes the current campaign unplayable. So I wanted to report them and also ask if anybody has an idea how to fix them.

For the bigger issue:

I am currently playing the Operation Olympic campaign as the Americans. After my opponent mailed back the save file after his initial turn I get a blank map with only one hex. Everything else is just black. For some reasons the Encryption key still works but except that there is nothing else from the campaign visible (strenght, VP, losses etc.). Tried fixing it by having my opponent send me the file again, having him replaying the turn and sending me the file and even reinstalling the game but nothing helped. Did anybody have a similar experience and knows how to fix it? Or does anybody have an idea what else I could try despite restarting the campaign?

For the other issue:

If you host a PBEM game for the normal campaign and choose the Japanese as your side, the Rocket ships of the American player will be withdrawn before he can use them. Here obviously the issue is solved by having the American player create the match.

Regards,

Secret

Edit:
Apparently for the first issue the map which was previously open is loaded without any units on it except the campaign safe file. So for example if I open first a campaign Scenario and load then the BTE file, I get the map of the previously opened campaign Scenario without any units on it.
