Yippeee!
Got GPSResults working in Ubuntu 14.04 in wine. Just had to install Manfreds "windows redistributables" and it works fine.
A year or so ago it was like Realspeed, the trial version loaded but didn't produce a machine code, so couldn't be licensed. But now it comes up with a machine code and Manfred's key unlocks it. Not sure if it's a wine development or something Manfred's done, just glad it works.
