Unless you had the online service where you shared your settings with other GearBox users (Tonelocker IIRC) then retrieving your settings from PT is your only option, and then you may have to write them down and re-do them in your current DAW.
It might be a different story if you were using Pod Farm as a stand alone. This what I usually do if I make my own patches since it is saved in the Line 6 app folder.
Check your Line 6 folder and see if a copy of your settings ended up there. You may be able to either copy into the plug-in or just make a new setting.
