PlasmaShop crash

I just got an error from PlasmaShop 2.2.6 today (I'm still using it because version 3.0 can't read PAK files).
I don't get this error on version 3.0, and restarting the computer didn't fix it.
So, when I click on it a window pops up:
"Access violation at adress 004AB31F in module 'PlasmaShop 226.exe'. Read of adress 00000000."
Any idea ?
That's quite bad, because there still are some file readable only by version 2.2.6.
Well, I guess for now I should better download UruPython again...
