This is a bit tricky to debug with so little information.

Can you share your CEP file ??  Send it to collectearth  [at] gmail please

Also you should post the error log (the last messages) that you can find in :

**C:\Users\YOUR_USER_NAME\AppData\Roaming\CollectEarth\earth_error.log**

Error log so that you receive an error.

Sorry for the late reply,

I think you are trying to import a CEP file byusing the Tools->Import/Export Data menu in Collect Earth.
This is not theway to do it, that menu is just thought for importing DATA not project files.

In order to open a project file CEP in Collect Earth you should just double click on the file, or alternatively go to Tools->Properties and in thedialog moveto the Projects tab and there you can choose the CEP file.
