Stuffit Expander

I downloaded the free Stuffit Expander in the hopes that it could run under Rosetta. The application loaded fine, but when I tried to convert a .rar file, it said the file was corrupt. I tried it on an old iBook G3 and it worked just fine.

Just wanted to know if anyone else has had any seucess or failures with the app, and if they will be releasing a universal binary of it soon, as the site says nothing about it.
