BlueIce2, I wonder if Victoria 4.1 uses compressed obj files (e.g. obz).  Vue has had trouble in the past loading these files.  The other thing to check is to look inside the V4.1 CR2 and see where object file resides.  You can find this path at the very top of the file.  I haven't downloaded 4.1 yet and I doubt if I will given that there is little to no benefit of this update over the previous version.
