What should I do about this?

[John]

When I made a map for the mod SverigeVsDanmark in Thorgrims Map Editor and was going to save it, it complained over my large amount of forests, and then I opened it again - almost all towns where gone!

I had renamed alla towns. 2 was still there.
The player start location was still there.

Thing is: I did the mistake of changing the Native map... I can't play the Native now!
What do I do?

Re-run the .808 intstall. You won't lose any data except for the changes you have made on Native. Then upgrade to .808 and everything should be fine.

Thanks!

You saved my day!
