If your track failed to upload, a manual upload will get everything back to normal, and allow you to analyse it within our portal.
Once you've opened the track detail view, click on the cloud icon in the lower tool bar. If the icon is disabled (it looks faded), check you've got your Rowlytics username and password entered into the app settings.
On pressing the upload icon, the file will be uploaded, if the file already exists, you'll be notified, and the file on the Rowlytics analytics portal will not be overwritten.
