Hey all! You're probably already aware since this post is a bit late, but there were some wires crossed in the code right before 1.24d released that were causing a good half of the op09 cards to not work properly, so 1.24e was released shortly afterwards. If you are/were on 1.24d Windows, it should've auto-updated for you! Otherwise, links are in the usual places.
There is one big hiccup for Mac users though, and it's that for whatever reason the 'File Read' permissions on the archive are no longer being saved properly. Which means until I can figure out the root cause of this, Mac users will need to do a couple more steps for this update:
To fix the "OPTCGSim is damaged" issue on Mac, you'll need to add Read Permissions to the app:
Put the Sim into a folder, and that folder into "Applications"
Right-Click the folder and click on the "New Terminal at folder"
Copy and paste this command into the terminal - don't run it yet:
xattr -r -d com.apple.quarantine (MAKE SURE THERE'S A SPACE AT THE END)
Open the folder where the Sim is in on a new tab and drag and drop the sim into the terminal. That way you get the correct Application Path
Run the terminal
