If I had to guess, I'd say the file is corrupt.

However, when I go to import a city, your city does not show up as an option. I downloaded your sc4 file and saved it under the Downloads Region folder.

Open your Downloads Region, select a small city square (has to be a small one), select 'import' and a list of the sc4 city files you placed in the Downloads folder will show up as options. To modify an existing neighborhood - the sc4 file - it's just a matter of importing the sc4 file into Simcity4 after placing it into that Downloads folder. Then you put your sc4 files in that folder. First you have to create a Downloads folder and place it in your Simcity4 Regions folder. I use Simcity4 to create neighborhoods or modify existing ones.
