I have been having this problem too. I was able to reset my download for M3 SR2 at Daz, but this didn't help any. I bought the body morphs a LONG time ago and I'm sure I had the latest version, but I lost everything original I had in the great hard drive crash of 2007 :(

So now my M3 body morph files are ones I salvaged from my Poser runtime backup. I guess these could have become corrupted.

So I will have to write a very nice email to Daz tech support and see if they will reset my body morph download for me...
