convert positioned jpgs to jpgs+worldfile or hgr with batch convert

Hi.

I`m having a serious problem when converting raster files with the raster manager's "batch convert" tool.

 I´ve a number of .jpg images possitioned in the model space, the number varis betwen dgn files, is about 5 to 75 raster files per dgn.

 Once georeferenced,  I need to export them to .cot or preferably to .jpg with .hgr file.

 When saving each file individually;  doing file>save as> imagename.cot or imagename.jpg+hgr file, it exports the file correctly. In the case of the .cot, it adds the position, scale and rotation in the header an in the case of teh jpg writes correctly the hgr file.

 BUT, heres comes my problem, after a batch convert processing,  when importing back the generated files to the raster manager, they appear in an incorrect position, VERY far from where they should be.

Even stranger is the fact that some times it has worked during the testing process.  

 I'm getting crazy with this problem, and soon I'll get quite  in a hurry seeing drafters lose time saving files individually.

 Please, give me a hand with this.

 Bye.
