ever come across this at xda? i'm assuming it's not what you use to input because it says to get rid of letsjapan. i'm wondering which way i should go.
edit: i found a workaround that doesn't have any drawbacks... mobem's ce-star now works on the touch pro. you can read japanese on opera mobile/ie... you can also read and write emails in japanese... all for free...
they only make you pay if you want to do advanced hand writing recognition or chinese input. that software is kinda wonky anyway. after the 15 day trial expires, you start getting this annoying dialog after soft resets (asks if you want to register or uninstall software to gain more features). you can get rid of this by deleting the dynanls.ink from the windows/startup folder...

(chinese is pictured above but you get the point)
i'm still kinda interested to see what your software looks like tho.. to see which of the three work best
