R4I SDHC Help

I was updating my friend's R4 with the latest R4i V1.45b English and when I was testing it;the games all stopped playing saying 'savfile not found please reset system'Can someone please explain how to fix this?

Well, are you sure the r4 card you have can use the V1.45b firmware ? if your card is R4i sdhc or r4i sdhc 3ds from r4i-sdhc.com, you can use the V1.45b, if not, you need to find the correct firmware. Is this your card : http://www.digitopz.com/red-r4isdhc-upgrade-revolution-for-dsndsindslnds-p-71.html and looks like this Another, what is the firmware of your DSi or 3DS. did you do any console update before that. More details.

I actually deleted something in the r4i folder so I downloaded it again so it's fine now, thanks for the input.
