Unable to import Car Care exported entries

I exported data from Car Care on my iPhone 3G and am trying to import it into the Car Care website so I can load the data on my new iPhone 3GS. When attempting to upload the data to the website I’m getting an error, unfortunately it doesn’t tell me what the error is, it simply states:

Step 3: Get your vehicle code and passord

Sorry, there was an error with your input. Please try importing your data again.

I've been trying to get this data imported for 2 weeks. The data is copied and pasted from the export file emailed to me from the application's export process.
