R4 cheat code editor problem

The cheat code editor for the R4 only works with the supplied usrcheat.dat file that only comes with 3 games. If i want to use a different one (which i downloaded from GBAtemp) it does'nt work and a system thing comes up "windows must shutdown this program" why does this happen?
Thanks ;)

Google r4cce (Or go to this link: http://home.usay.jp/pc/soft_en.html ) by yasu and click the first link, click on r4cce.zip to download.
Whit that one you can modify your CheatDatabase.

Thanks man!
