Problem Syncing Particular Cookbook or Recipe

When a particular cookbook is giving errors when syncing, you should replace that cookbook with a new one.
 
So, go to your online cookbooks web page here:
 
https://www.mastercook.com/app/Cookbook
 
Download the online cookbook that is not syncing properly and save it as a file to your computer.
 
Then open the file you downloaded. MasterCook 24 will ask you to save as a new cookbook on the computer. Do that.
 
Then sync that new cookbook. If that new cookbook works better, then delete the one that is unable to sync properly.
