I've recently downloaded an addon plane to my FSX stable which seems to have corrupted my PMDG B747-400(Passenger and Cargo) and MD11 aircraft. When I try to download a B747-4 saved flight, or set up a new flight I get the following error messages in turn; PMDG_74700_Main.DLL cannot find PMDGOptions.DLL PMDG_74700_ACS.DLL cannot find PMDGOptions.DLL PMDG_74700_Overhead.DLL cannot find PMDGoptions.DLL When I try to download an MD-11 saved flight, or try to set up a new flight I simply get the standard message 'Microsoft FSX has encountered a problem and needs to close down'. This is causing me no amount of frustration as I predominantly fly the PMDG 747 and MD11 the whole time. Does any one know what a fix might be? If,as I suspect, it may be to download the PMDG software again, then I've got the MD11 on disc, but my B747-400 was downloaded from the PMDG server and my download period may have expired. Any help would be gratefully received. Regards Bernard PS. There are no other planes in my stable which are affected - only my PMDG aircraft.

Leffe, Many thanks for your prompt reply. I'm no computer expert but I'll give the troubleshooting information a 'go'. Why can't the addon suppliers give this warning in their product information? Thanks Bernard Walford

Bernard!Those have had this issue sent a ticket to Ryan and he usually fixedit for them, if it belongs to that probs. in the link. Try a ticket if you think it´s to complicated, I´m sure he will help you.You must however monitor your ticket for an answer. / Leffe

First thing to suspect when there is a trouble launching FSX is the dll.xml file may be corrupt. The link to the knowledge base article is here: http://support.precisionmanuals.com/KB/a92/dllxml-information-and-troubleshooting.aspx If you have installed something from Wilco then pay particular attention to the section on CR and LF characters. Hope it helps.

Thanks to you both for the links to the DLL.XML troubleshooting information in the PMDG support library. I've located the DLL.XML file in the directory, but when I try to open it I get the message: 'XML page cannot be displayed. Cannot view XML input using XSL style sheet. Please correct the error and then click on Refresh or try again later'. I assume that if I try to fix the issue myself, or pass via a ticket to Ryan, I need to display the page correctly. Do you know how I might do this? Thanks once again, Bernard PS. The addon causing my problems is the Razbam A7 Vought Corsair Vol 1. from Flightsimstore. Wish I'd never bothered. I don't think i'll be getting Vols 2 and 3.

Did you d/l the "Notepad++" ?/ Leffe

Leffe, No I didn't but I will do so shortly. I didn't recognise the description in the troubleshooting information for downloading Notepad++ would apply to the message I was getting. Thanks again, Bernard

I've finally sorted the issues with my corrupted dll.xml file, bit it's taken a week of effort, and the assistance of Ryan at PMDG, to sort this. My message would be that if you are unaware such issues exist, and, if PMDG aircraft are your main interests, then steer clear of add-ons - unless, of course, you're a computer expert and know what you're doing.Thanks for assistance.Bernard
