Glad that some of you got it to work.
Regarding Mediafire: It seems there is a regional problem with download links. There have been numerous times people have complained to me regarding corrupt links but ALMOST every time I checked (P-40s being the exception), the link has been fine my end. That is why I am now trying to post an additional link at a place link Mission4Today in an alternative format.
With 7zip archives, you can only use 7zip to open them properly (don't work properly with WinZip or WInRar, as codec are different). I prefer 7zip as it has an excellent compression codec and I've found it to be much more resilient to corruption than zip or rar files (probably owing to its lower file size).
Anyway I'll clean this thread up tonight and post the M4T link. As for the 'belt' bug, DBW1.71 has JetWar v1.2 but lacks the updated pilot models available in the stand-alone version. Hence it seems if you are running vanilla DBW1.71, you may be missing the 'belt' texture. To be safe, I might reupload the archive with that 'belt' texture included
