Hi Grumpydlw,
As far as the loading of savegames is concerned, it must have something to so with the execution of some script when the game is loaded:
1) Are you using some plugins (3rd person, 360-degree panorama, or another plugin)?
2) Do you have any script under the "Advanced" tab of the "Project Properties"?
3) Are you using the "Set Resume Locations" feature?
4) Did the error start occurring recently, or has it always occurred for the 2 years?
5) Does error occur also with other projects created with Adventure Maker (like the sample games that use scripting)?
As far as the compilation error is concerned:
1) Did you try to reinstall Adventure Maker?
2) You can get the missing files from the following URL:
http://www.adventuremaker.com/systemfiles/
(right-click on a file and click "Save target as...")
Oleaut32.dll and Olepro32.dll should be in the c:/Windows/System32 directory
