Hacking Ewin2 and SuperKey

[Izair]

Hello, first of all, sorry if my english is a bit bad.
I have my new DS lite.
I use EWIN2 (with the ewintools program) in the slot 2, in the slot 1 i have a card called "super key".

My problem is that, i can play the games and save them, but when i reboot the game i can not open the game saved, so i have to begin the game again and again...

Is because ewin2 is not compatible with the superkey? what should i do??

Thanks!
