Just to make sure, the way to get the patch it do go into the Itch.io directory and re-download the software?
The itch.io client must update the application himself when you enter it. Checked just now and followed the below algorithm:
1. entered into the library.2. chose there DM Helpmate and waited.3. The client started updating the application automatically
If he does not want to be updated, you can force him to.
