Hi PMDG Team and co-simmers.I've been reading all these numerous posts about CTDs for a long period of time despite the fact that I haven't had a SINGLE CTD expeirence with PMDG747 any version. However, this finally happened and here is my story.I was one of very first customers of PMDG737NG and was enjoying this bird for a long period of time. When 747 came out, I deinstalled PMDG737NG (just to avoid any possible conflicts) and insalled PMDG747v1.0 in August, than V1.1 in November. Everything worked smoothly with no CTDs as I mentioned before.Yesterday, driven by nostalgy, I decided to install PMDG737NG again. I did everything in accordance with FAQ on PMDG Support Page, namely1. Fully deinstalled PMDG747 via Add/Remove Programs, then manually removed PMDGoptions.dll from Modules folder. Deleted PMDG747 folder from DocumentsApp DataUserMSFS9Aircraft. Restart PC.2. Installed PMDG737NG, then restart PC. Installed PMDG738/39, then restart PC again. Checked 737 performance, did couple of flights. Everything worked nicely.3. Today in the morning I installed PMDG747v1.02, then PMDG747v1.1 AND...Now I having crashes to desktop while loading 747 panel. The module is to blame - PMDGOptions.DLL (according to Windows ERROR message)4. So, i decided to check to deinstall both 747 and 737 using Add/Remove Programs and 737Remover respectievly.5. Then, I did clean installation of PMDG747v1.02 and v1.1. Guess what? Works perfectly like a swiss watches with no CTDs.Summarizing all the mentioned above, my observation lead me to conclusion that there are some technical problems with PMDGOptions.DLL file. To be specific, it seems like the module doesn't work adequately with both 737 and 747 installed. Either PMDG747 or PMDG737 alone works OK.My system specs are:P4-3.2HT with 800FSB1024MB DDR320RAMRadeon 9800PRO 128MBWin XP Professional (with SP1 only)Thus, I would appreciate if you look into this issue more preciecely and let us know what might be done to resolve this issue or what steps we (users) must implement to male things work right.Sorry for my ultra-formal English (I am not a native speaker)Awaiting your reccomendationsBest RegardsDmitriy Toropov.

have you installed the F1 view utility?

I removed it a year ago.

rgr that

I wonder if this has been an issue for me. I've yet to find a solution to my CTD problem with the update, but saw that I needed the NG installed first before the Queen. When flying the NG and accessing the options tool, I get choices I'd think would be greyed out, like reseting fire bottles and such.
