Hi all, installed the CRJ200 version 1.4.5. on a iMac7,1 OSX10.6.8 with 3GB RAM 128VRAM only to find that the PDF and MFD stay dark, no matter what I do (ext. power, APU, engines running w/ generators connected, etc.). I reinstalled the CRJ200 to no avail. Gizmo.plugin dates back to 9.10.2013, CRJ200.acf dates to 2.4.2012 - is that causing the problem? I already repaired the file access rights. My parallel installation on a MacBook Pro with (nearly) the same specs still does work. Mirroring the HD with the XP9.7 installation to the iMac did not work. Is the graphics card of the iMac causing the problem (ATI RadeonHD2400)? I want to run 1.4.5 of the CRJ, because 1.5.x won't run on the weak hardware. Sorry for this vintage stuff question, but me is trapped on that very system. Unfortunately... Am clueless. Got ideas? Cheers, Mike
