Same Here. I have
all invalid share.
I use x86 version and running with GT 630M (Avg on 1200 kHash/s)
Here the loading screen

Could you please download the "debug" version from the dropbox folder and post the info from that? It includes additional information that will make troubleshooting easier.
Debug version didnt work for me, i think its x64 and my windows is 32bit (x86)
Thanks for fast respond
