HTC Hero :: Viewing Market Apps Orange UK

have recently received Hero (Orange UK) as upgrade.Followed the incredibly helpful Tips & Tricks thread to get phone set up at it's best.Have been very impressed with phone, but have come across problem that's puzzling me. Have been trying to download FingerPlay MIDI from the market, but can't navigate to download page on phone. Have downloaded various other apps from market successfully. Contacted developer who has been very helpful & he's done all possible at his end to make app visible. Have read some threads regarding visibility of certain apps in market & problem with Orange network. Does anyone know if this is still an issue? Could any other Orange UK customers take a minute to see if they can see FingerPlay MIDI in market?As long term MIDI music user this is an app I'd love to try.
