Stephano,
If my memory serves me correct there were problems with CSA aircraft on the data which came with your system, that is what is making me think that you are using the earlier database.
Do you have more than one version of the radarbox software on your computer, perhaps an earlier version which may have had its d/b updated instead of the version you are using. If you have upgraded to V3.13 or V4.03 since you bought your box you will probably have more than one version of the radarbox software in your computer. If you go into your airnav folder in my computer you should be able to check how many versions of radarbox are on your computer and ensure that the latest d/b has been installed in the correct location. for the current version.
If the lastest d/b is not in the correct data folder I would suggest that you download it again and direct it to the correct location, or copy it across between versions
