When using the QMB with e.g CAN-Channel , scramble mission I always receive a "Corrupt Data 1" window.
So, I clickon O.K. , then on Reset red button , but Nada ! The window of "all the corruption " still pop up.
The same happen with a lot of maps.Some like "Zapolare" seems not to be installed ( like the window says ), although this map appears in the FMB under "North Norway".
So, I am a little bit confused... can you ease may pain ?
Thanks a lot for all your past , present and future work for the community .

The QMB mission set included in DBW v1.0 is not the best possible. For example, your Zapolare issue is just that the missions use old loading path for map and that path is now different in UP3 and DBW. Similarly, The Slot map is now replaced with Solomons map and missions trying to load The Slot map won't work anymore. If you want to fix that yourself, all you have to do is to open all.ini in MapMods folder, find to correct map loading path there (second part of line) and then open faulty missions with text editor and replace the path after MAP word in the second line of mission file with the correct path you can see in all.ini.
There are also some mission sets for maps that are not included in DBW now but should appear later in DBW map add-on packs. To play those missions you can either install that missing map yourself or wait until it appears in some DBW update.
Then there are faulty missions loading NWEurope map with several names, for example Kt_eastafrica and fly_Z_BOB_A, so you can just remove those faulty mission folders if you want.
Then your CAN-Channel issue is that those missions actually have 10 flights, not 8 or 16 like old or new QMB missions. Old QMB+ and QMBpro mods for v4.09m based games like UP2.01 loaded those missions without issues, they just let you edit first 8 flights in QMB and all the rest flights just appeared in mission with those planes specified in mission file. Now this new QMBpro version doesn't like missions with non-standard number of flights anymore and gives you "Corrupt Data" messages.
I hope that better QMB mission collection is released soon and I already worked with it a bit yesterday and posted my cleaned collection at development team forum. So stay tuned for updated QMB mission collection and don't worry about missions that don't work now. If some mission gives some error before even starting to load, then it is just a problem with that mission, not with your PC, IL-2 settings or DBW installation. If you want to help us with fixing and testing QMB missions, then you can PM me or CirX and send fixed mission files or lists of faulty missions.
