Sorry mackenzieh that i didn't get back to you very quickly on this.
Yes you have to use 32 bit 8BF plugins for PSPI as its a 32 bit plug-in.
Tom you will need the PSPI plug-in i attached it here.
Attachment:
pspi.zip [19.46 KiB]
Downloaded 435 times
This executable is for WINDOWS only.
Place it in your plug-ins folder
Restart GIMP
Look under Filters> and find the new menu entry Photoshop Plug-in Settings and click it.
A new dialog window will open
Point the plugin to the folder you placed the 8BF filters in.
Restart GIMP
You should now have a new menu entry under Filters named Xero
You also should have a new rc file in the gimp user folder. "pspirc"
My advice is to use my method of adding Adobe (8BF) filters to PSPI.
Use subfolders of each new plug-in and point PSPI to each one as you add them. Creating multiple lists of directory paths works much better than one directory where you just throw in a plug-in and hope it works. Most of the time it will not unless you create a separate directory for each 8BF filter set.

Good luck and holler at me with a PM if you need further assistance.
