Anyone remember Ascent, the ride log software?

[PsiSquared]

Do any Mac users remember Ascent, a ride log app for Macs that was sold by Montbello Software? I've got a few years' worth of ride logs for that app, but they are in a funky file format, .tlp. I no longer have the app, and I don't know how to find who wrote the app. I can't find anything online that would convert from a .tlp to a .tcx or .fit format. Opening the files in text edit isn't helpful in the slightest.

Does anyone still have this app on an old Mac?
