Thanks for the private e-mail with an example file.<br><br>The 2.21 betas (both beta 2 and beta 3) have a problem loading .PPS files (as opposed to .pp2 - the new file extension and format). I fixed this problem about 4 weeks ago for the next release, but I'm working on one particularily insidious oddity that's blocked me from doing the next release, so it's not available yet.<br><br>A work-around for this problem is to use version 2.20 (you can install 2.20 to a different directory if you want to continue to use 2.21 for new data) to load the .PPS files you want to use - and then save these files (with version 2.20) in the new file format (.pp2 extension). You'll then be able to load these .pp2 save files with version 2.20 or any new version (including 2.21 beta 3).<br><br>Thanks for the report on this!<br><br>
