I agree, but I can assure you that this configuration worked with some units. Check maplaunch.ini file on the root - it doesn't point to any parent dir. In fact in the past, when I helped one user, he posted sreens from his original SD and the structure was exactly the same and it was a surprise for me also. Anyway, PGANKER should test your recommendation also.

@PGANKER
Create a folder Mobilenavigator on your SD and than move all files and folder inside that folder, than try again.
