Conflict with custom node theme + clear cash

First I would like to thanks everyone who work in this module because its really very nice module.

This is my first time I use this module , After I install it I had 2 problems

1- I keep get error msg when I clear cash

* The selected file C:\xampp\tmp\fil998.tmp could not be copied.
* The selected file C:\xampp\tmp\fil999.tmp could not be copied.
* The selected file C:\xampp\tmp\fil99A.tmp could not be copied.

2-I have node type called mimage , I add custom template for that node type called node-mimage.tpl.php , and clear the cash using drupal and manually , but drupal still used node.tpl and wont override it.

After I take off the ad module everything work fine again .
Thanks
