PFD and ND gauges "sticking"

hi!i've got another problem: after I have reinstalled my FS9(.1) all the PMDG displays and the FMC stay black although i can start a completely normal engine startup procedure.Almost the same configuration is installed at FS2002 and there it works without problem...The problem is the same at 600/700 and 800/900. Installed Service Update 2, then the 1.2 -> 1.3 and the 800/900. And even if i check after every step of that installations, the problem cannot be solved.Another problem is, that he tells me, that the PMDGoptions.DLL is not a valid prior version and can't be updated. Maybe there is the problem hidden?Config:Win XP - P4, 3,0GHz, 1024MB DDR Ram, ATI Radeon 9800XLHope you can help me, because I love that plane...GWG009
