Air Canada regional flight plans

Hi all,I have been slowly updating my ai in FSX and have downloaded the 2 Air Canada files that were recently in the library. I have the main Air Canada traffic working the way it is supposed to but am having problems with the regional flight plans. I have all the planes that are required for the flightplans installed and the aircraft titles the way they are mentioned in the included text files. I can compile the files properly into the bgl file using ttools with no errors. When I load FSX it will go to 90% load where it starts loading the traffic, it will sit there for a little bit and then say that FSX has encountered a problem and has to close. I would imagine that the flightplan file is ok as it compiles ok. My question is, does ttools look to make sure the required aircraft are in FSX when compiling? Is there a problem with the aircraft that I am trying to use? They are PAI Dash 8-1 -3, CDAI CRJ-200 -700, HTAI B1900. Do any of these have compatability issues with FSX. Thanks in advance for the help that you can give.Tony
