Quote - I think it may be related to installing V4.  I got the error too but only after installing V4.  It did not come up the first time I opened Poser because I had not added her runtime yet.  It came up the next time I ran poser AFTER adding her runtime to my list.  I just started Poser up again (because I foolishly clicked 'ok' the first time) and I didnt' get it again.

I don't think is V4 per se, as I've not run into this.
The one recent item that I don't have that's V4 related is the Immortal Dream hair, but this is probably just a coincidence.

Also can you all check to make sure you are using the latest version of Poser (6.0.3.139).
