I had been using Brawlbox to edit a .pac file for days with no errors, when suddenly I was unable to open it again. All I did was exit brawlbox and test the file on my wii. It can open a backed up version of the file from a while ago, but sadly neither the current version on my computer nor the version on my SD card can be opened. My error looks like this

If you downloaded the "PSA 2.70-1.90" pack provided by this site under the "Resources" tab, then you shouls have a text file that says "ALL ABOUT PSA P1"
Open it up, press ctrl+F, and type "Flags values:elemental damage"
Those are the attack effects.
Go to the moves that freeze the foe in-game(Ex. Attack11, SpecialN, etc. Correspondant to the motion file.), and change their elemental effect from there.
and make sure you did not somehow corrupt the file
Which can be easily done if you save directly to the desktop instead of the external memory device(s).
