I seem to be having problems opening projects which contain GIS data (I think its only when GIS data is present). I am new to SMS, having worked with some tutorials only before today. I have had no problems opening saved files with tutorials. When trying to open SMS 10.0 when a GIS file is in the project I get the following error message: "SMS 10.0 - [untitled.sms]: sms100.exe - Application Error The exception unknown software exception (0xc06d007e) occurred in the application at location 0x7c812aeb." It doesn't matter if I hit ok or cancel, SMS closes and I am unable to access the previously created project. This seems to be confined only to projects which have GIS files. But, I am not sure about that. I have worked with tutorials, saved the projects and re-opened them without any problem. I am using is registered/enabled version of SMS 10.0 from a disc purchased last fall. I downloaded the latest software update 10.0.10 before starting. I have a licensed version of ArcMap. Any suggestions? Thanks in advance.
