Indesign CS3- plugin issue

Question

I'm having a problem with Indesign, within Adobe Master Collection CS3 in that when it's started up it comes up with an error message stating that the application or DLL "Sangamexport.apln" is not a valid windows image, and says to please check the installation diskette. This also causes Indesign to crash when right-clicking on a line or anything else drawn.
This issue cropped up after updating to the latest version, as version 5.0.3 works just fine, however version 5.0.4 does not.
While disabling the plugin does resolve the issue, being a site licence (I work for a school with several hundred PCs on a network with the application installed locally), and every PC that has the latest updates has this exact issue, repeating this on each individual machine is impractical to say the least. Has anyone else experienced this issue?
The PCs are runnning Windows XP, service Pack 3

Jitendra:
   While not specifically addressing this problem, I have obtained the UID (and then derived the UIDRef) of an image by getting the hierarchy interface of the container and then getting the child.  This is a snippet of the code:
    UIDRef ItemRef = UIDRef(db, ItemUID);  //  ItemUID & db (IDataBase *) passed into function; db
    InterfacePtr<IHierarchy> iHierarchy(ItemRef, UseDefaultIID());
       if (iHierarchy != nil)
          if(iHierarchy -> GetChildCount() > 0)
             UID imageuid = iHierarchy -> GetChildUID(0);
HTH.
