Those errors look to me like you may have a corrupt project file.
Try the following to fix the problem (assuming you are using the new editor):
Rename the existing .dbpro file (doesn't matter what to).
In the 'solution explorer', locate the 'Untitled.dba' file, right-click it, and then delete it from the project.
Right-click on the project and select 'Import existing file'.
Locate your existing .dba file and click OK.
Select File->Save project as, then navigate to your project folder, name the project appropriately, and then click OK.
Now try and compile it again.
If you are using the original editor, then simply rename the .dbpro file, double-click the .dba file and then allow the editor to create a new project file for you.
