Drobo

Time tamer

Trying to use time tamer so that I can use time machine for backups without it taking up my whole unit. Running snowleopard 10.6.1 on a macbook pro. Drobo gen2 with latest dashboard & firmware versions. Downloaded Time tamer and double clicked on the app. The application seems to have launched and a small wheel is spinning on the top bar of my screen. However nothing else has happened for 15 minutes & the windows to make sparsebundle image shown on the timetamer site have not come up. Is this a snowleopard problem? Is there something else I should be doing?
I would really appreciate advice as so far Drobo is more complicated than it seems superficially!
