Mapsource cannot find TDB or img (preview map) file or TDB and imf (preview map) is not valid. Check your registry TDB and BMAP if each file is present in your HD

The TDB and img files are there where they should be. The registry is correct. I suspect TDB or img files are not valid. What could be wrong. I followed the latest instructions in post above and also used 1.18 ver of Mapsettoolkit. The only difference is I am using a Mapsource map (from Garmin Canada Enhanced CD) instead of creating my own. All I want to do is make it transparent.
