R4 Firmware Problems :/

So I just left on a road trip the other day....brought my laptop and my ds along (I have an R4 SDHC) I haven't played my R4 or my Ds in a while and thought i would entertain myself with some new games on the R4. I put on Sims 2 and Theme Park. I'm having fun with both of them, but for somereason now. None of my other games are working, everytime I load them up, it says sorry can not read saved data. I even have Ghost Busters on here and I didn't have a save game file created yet, but once i created one....it couldn't read the data. Ive tried so many different firmwares like YS Menu and Wood R4 but when I use those....the games don't even load. I would like to keep my R4 and wouldn't want to spend anymore money, can someone help me?......P.S. They all work on my Emulator

Why don't you buy an R4? it's one of the bests and not very expensive

Just Format Your Card Using Sdhc Formatter Then Download New Kernel From The Site Of your Provider then Copy It To Your Card..
