Can't move any applications to SD Card- "Couldn't Move App" error

I'm trying to move any application that I install to my SD card (Nexus S, so its technically internal storage) and regardless of what I choose, I get a "Couldn't Move App" error. I fired up logcat and got the following output: I/DefContainer( 1273): Copied data/app/de.joergjahnke.gameboy.android.free-1.apk to /mnt/asec/de.joergjahnke.gameboy.android.free-1/pkg.apk D/VoldCmdListener( 81): asec finalize de.joergjahnke.gameboy.android.free-1 E/Vold ( 81): Failed to chmod /mnt/asec/de.joergjahnke.gameboy.android.free-1 (Read-only file system) E/Vold ( 81): ASEC finalize mount failed (Read-only file system) W/Vold ( 81): Returning OperationFailed - no handler for errno 30 I/PackageHelper( 1273): Failed to finalize container e.joergjahnke.gameboy.android.free-1 I/PackageHelper( 1273): Forcibly destroying container de.joergjahnke.gameboy.android.free-1 D/dalvikvm( 250): WAIT_FOR_CONCURRENT_GC blocked 0ms E/DefContainer( 1273): Failed to finalize de.joergjahnke.gameboy.android.free-1 at path /mnt/asec/de.joergjahnke.gameboy.android.free-1 D/dalvikvm( 250): GC_EXPLICIT freed 48K, 26% free 14596K/19591K, paused 4ms+5ms, total 64ms D/VoldCmdListener( 81): asec destroy de.joergjahnke.gameboy.android.free-1 force I/PackageHelper( 250): Forcibly destroying container de.joergjahnke.gameboy.android.free-1 D/dalvikvm( 250): WAIT_FOR_CONCURRENT_GC blocked 0ms W/ActivityManager( 250): No content provider found for permission revoke: file:///data/app/de.joergjahnke.gameboy.android.free-1.apk D/dalvikvm( 250): GC_EXPLICIT freed 13K, 26% free 14595K/19591K, paused 3ms+6ms, total 63ms D/VoldCmdListener( 81): asec destroy de.joergjahnke.gameboy.android.free-1 force E/Vold ( 81): Couldn't find ASEC de.joergjahnke.gameboy.android.free-1 I/PackageHelper( 250): Failed to destroy container de.joergjahnke.gameboy.android.free-1 I/PackageHelper( 250): Forcibly destroying container de.joergjahnke.gameboy.android.free-1 D/dalvikvm( 250): WAIT_FOR_CONCURRENT_GC blocked 0ms D/dalvikvm( 250): GC_EXPLICIT freed 8K, 26% free 14594K/19591K, paused 3ms+8ms, total 69ms I/PackageHelper( 250): Failed to destroy container de.joergjahnke.gameboy.android.free-1 D/VoldCmdListener( 81): asec destroy de.joergjahnke.gameboy.android.free-1 force E/Vold ( 81): Couldn't find ASEC de.joergjahnke.gameboy.android.free-1 It seems to be a permissions issue of some kind. I've tried booting into CWM and resetting permissions, but that doesn't seem to do anything. Even re-formatting the storage doesn't seem to do anything. If anyone has any advice, I'd greatly appreciate it!
