I put this together, it's quite self-explanatory.
Open the zipped file in Excel.
There's a giant button that says 'Import OPO File'. Click the button, load your file, copy, paste. It's that simple.
Like I said in my last post, I'm not sure if the 2.53 OPO decks will load up in this software, since I'm using 3.1 - If you're using 2.53 please post any errors you're encountering in the comments.
