Hello salamzaban,
When you change the template, the module positions will change. It may be that the position you had mod_html in does not exist anymore.
Try placing it in the "left" position first, as that usually is in every template. Then move it to an available position.
If you use Joomla1.5 the template should tell dictate which positions are available, and this should be apparent in the module manager (when editing the module). You should see a set of positions that exists only for that template.
