I just reinstalled WebMO Pro 10.1 on a brand new Windows 7 (64 bit) machine. When trying to see if I did everything correctly I ran a Molecular Orbitals calculation on CO2. The output makes no sense and when I click on the magnifying glass to view an orbital I get a pop up error. I have included screenshots of both.

I am using Firefox 15.0. Do you have any thoughts about what I have done wrong?

I strongly suggest this has to do with Perl. The most recent version of Perl (I believe 5.10 and higher) removed a key feature that I had been using in WebMO.

In the most recent version of WebMO (12 and 13), I resolved this by re-writing large portions of the code, such that WebMO 13 is now compatible with all Perl version.

If you do not want to upgrade from WebMO 10 - > WebMO 13, the alternative is to try and locate an older version of Perl (5.8 should be OK, I believe). This should likely resolve the issue.

I suspected as much. We actually have a order submitted for WebMO 13 Pro.
