When you installed the program on a new machine, all the settings were set to default. This means that the predefined directory was automatically scanned for files to be imported. In order to import the data, you need to specify the directory that should be scanned. Regarding this, in order to access your files, you should make sure that the directory has write permission active. Also, when using a network share, like your case, it's advised to use the UNC path (i.e. \server\share) instead of mapped driver letters. For more information, check the Help menu inside the program.
