If you got a copy of the project from one of your colleagues, you will need to check if they don't have a different version of ConQuest (5.1.0.0 or higher). If that is the situation then please continue with a support member for further assistance.
ConQuest crashes when trying to open a project
I'm having some difficulty accessing a project in ConQuest. When selecting the project, the program appears to process as normal but then suddenly crashes without any errors.
