Ok ive had this problem since yesterday when me and my dad networked our computers.havent been able to fight why?

and you COULD fight b4 yesterday?

well.. check the faq...

even though there is a new version out, the network code in the game has not been changed/touched....

Ya i fixed it but now when i fight it takes forever!for me to cause damage to anyone im fighting but as soon as they hit me i take damage quick.it cost me a fight already i lost to that buster megapower!my supers went right thru him!

well.. thats Lag...

i have NO doubt.. on his end, it was the same thing... HIS moves weren't taking away your damage...

try changing the settings in the options menu...
