Using IDW and getting a strange error

Sorry that should say IDW

Please Help!

I have a giant model built to create a raster by IWD from one shapefile (each ratser will come from a differnt field in that shapefile)
It WAS working.
Now I'm geting a strange error that I have never had before and nothing I do is making the analysis work.
I've tried my backup copies as well and I'm getting the same error.

the error is:

ERROR 999999: Error executing function.
General function failure
Item not found in this collection.
ERROR 010240: Could not save raster dataset to D:\Mapa2\Rasters_Geodatabase.mdb\Apr_2008 with output format IMAGINE Image.
Failed to execute (IDW (4)).

I don't know why it's using the format IMAGINE Image (I don't know what that is or how I set it to that or how I can change it?)
I also got an "already exists" error a few times, the mxd is set to allow for overwriting so that shouldn't be happening either!

Thanks so much in advance!

In a personal geodatabase, the raster dataset is converted to an Imagine (.img) file and stored inside an image database (IDB) folder. The IDB folder is located in the directory next to the personal geodatabase.

How raster data is stored in a geodatabase

I would recommend having your raster outputs go directly to another folder instead of the Personal Geodatabase. There may be an access issue with the IDB folder.
