Question about htc3600 trinity
 

I have the following problem with my ppc: So far i could use some of the 3d party keyboards instead of the built in microsoft one - i need Greek lang support. However, now my ppc doesnt seem to run any other keyboard besides the default microsoft. If i install a new keyboard it shows on the options and i can even change its settings, however it doesnt initialize. Whats worse, every time i boot i get the following message:

The file 'startkey' cannot be opened. Either it is not signed with a trusted certificate, or one of its components cannot be found. You might need to reinstall or restore this file."

other than that, my ppc runs fine. Any help would be greatly appreciated
