LR doesn't support pngs, I tried saving them as such and then importing them.

I use lightroom 2.4 as my main photo editor. At times when I need more noise reduction, I used paint.net as an external editor within LR. LR exports photos as tiffs then opens paint.net with the file or files I've selected and they are already opened in PDN. I do the noise reduction, and when PDN modifiles the TIFF, LR says it has problems reading it and that it is corrupted. Is there anyway I can work around this?
