Hi,
If I've understood you correctly, the issue is because of a mismatch in projection. Your shapefile or default is in one projection and the tiles are using WGS 84.
This is explained here:
http://www.mapwindow.org/documentation/mapwingis4.9/class_tiles.html
(see A. Coordinate system and projection)
You'll need to either reproject your shapefile to WGS84 or set your base projection to WGS84 (if your shapefile doesn't have a projection set).
