My Unisyn crashes when opening a "Performance"

[ifwuh]

HI,

I have a bunch of Unisyn1.14 "Performance" files, you know those "All banks and Patches" files that are now called "Snapshots" in Unisyn2.1.1

So I try to open one of these Performance files in Unisyn2.1.1
and it will hang for a little bit and then quit out unexpectedly.

This happens everytime.
The crash log starts like this...

Exception: EXC_BAD_ACCESS (0x0001)
Codes: KERN_PROTECTION_FAILURE (0x0002) at 0x00000000

All my old Performance files are useless?
