Make sure in the title it says CRJ900 or CRJ-900, get virtuali to confirm.
Sorry, CRJ-900 is not supported. CRJ-200, 700 are...the manual has a list with airplane models supported. If you have suggestions about missing models you would like to see, it might be helpful to know.
And yes, the "Title" is the relevant info we need to identity the plane, it should ideally include the model number. For example, if you have a 747 that is titled like: "My big fat 4-engine jet from Boeing", ParkMe will not be able to identify it. The system uses regular expression syntax to parse the title so, it should be smart enough to identify something like B747, B 747 or B-747 or Boeing 747 or PMDG 747, etc.
In any case, if you have a sample of an airplane that should be supported, because it's on the manual list of recognized types, but is not recognized, please post the title here, we might be adjust our parser to find it.
The good news is that ParkMe files are *very* small so, it's really easy to keep updating those without requiring to distribute the whole installer.
