Error Readin File Options

[sleepyto]

When I try to load a activity I get the following message, "File Not Found encountered while loading".

I am using Vista Ultimate 64bit. I have tried this using the UAC and with it turned off. I have also tried using it with run as adminstrator. No luck in any case.

Is this a 64bit issue?

Any suggestions would be greatly appreciated.

Thank You in adavnce.

As I mentioned before I have tried to download various activities from various routes. I have tried to download activities from all the default routes. Also I have tried to download from the new Bala Sub route, Bnsf Scenic Sub, C&NW. I had used AM before but when I went to Vista Ultimate 64bit I begain having problems. Maybe Opening a activity is a better word to use. All the route and activities work correctly when I run MSTS. Its when I try to open the activity in AM that I get the error about not being able to find the file. I have no Idea what file it is looking for other than the .act file that I try to open.
