A few questions about Pokerstat

Just a couple questions about Pokerstat:


Is it possible, when you buy the Low Limit version to upgrade it to the Professional version and how much does that cost if possible?


Is it possible (maybe in the future) to use handhistories from other sites as well? (for instance Pokerstars when opening for real money)


Thanks


Regards


P.S. I'm strongly considering buying the program. It looks very promising!

Can I keep, when my trial version has 1200 hands, the database when I register? I suppose so, just wanting to make sure.


Thanks
