I have patched recently a Wings Over Vietnam variant of the Strike Fighters genre and in the end, after applying all three patches it says v07.05.05, just as it says to you. You could reinstall the game and before patching look at the starting version. Perhaps the game was already patched with patches 1&2 and you only had to apply the third one. In this case before patching you should have v05.13.05. If this is the case, I guess everything is ok just installing the third patch.
If not (starting version is different from v05.13.05 and still you can only apply the last patch), then perhaps some of the "elders" here could help. I'm new here too.
