I keep having the same problem with Butler. Every couple weeks something on my card gets corrupted to where Butler can't play mp3s. It plays alarm tones & system ringtones just fine, but it crashes when I try to select an mp3 tone. I go to set the alarm, tap the 'select mp3' thing & it resets my phone every time. The only thing that fixes it is reformatting my card & reloading everything on it, which is a pain b/c it's 1 gig & I have a ton of stuff on it. Does anyone else have this problem? Is there a certain program that's known for corrupting SD card files like this? I have a lot of programs installed;
4cast
AutoOff
Button manager
Butler
Colortris
Destaller
Filez
handpainter pro
handyshopper
Icon manager
Keycaps
Khroma
Lightsoff
Moonphase
Mother(kind of like Butler, also crashes when I try to set an mp3 alarm tone)
mRing
NFP
Note Pad
Ectaco translator software
PiLoc
pTunes
Slovoed translators
Soundrec
Splashphoto
TCPMP
phone Technician
Textras
Verichat
Voice Memo(yoinked from my boyfriend's Zire 72)
Xiino
ZLauncher

Anybody know if any of these could be corrupting my files? Also, I had a bunch of other ones I downloaded to test out but ended up deleting. I run most of my programs from the card too, if that makes any difference. Any help is appreciated, this is driving me nuts.
