Thanks for telling me, i will take a look into that. Which windows are you using btw?

Can you download the last version and tell me what you see?. It should either show you an error, or render normally, or render readable but ugly text (in this case it is a drivers problem that i have no idea how to replicate to fix it).
if it still shows blank characters or nothing at all then i think i will know how to fix it.
