Turn back your system time for one month so you're back in April
Make sure you've got the newest version of MakeMKV and start it
Go to Help > Register and paste the April beta key (regardless if you've done this before)
Close MakeMKV and restart it
Start ripping - should work fine now
Set your system time back to normal
This worked for me.
But only on my 12 year old laptop with win7 and no internet
connection.
Tried the same thing on my win11 laptop but couldnt get it to work.
What did you set the date to? I just tried this on my Win11 desktop (internet connected)... removed my perm key, set date back to April 10 (after disabling 'Set time automatically') & applied the last beta key. Worked just fine, reporting a time-limited key.
"valid until end of April 2024" is rarely literal/precise.
1. In Settings -> Time & Language -> Date & Time
2. Change " Set time automatically" to "Off"
3. Select "Change" in "Set the date and time manually"
4. Jump back one month to April, select "Change"
5. Minimize the Settings window (optional) and start MakeMKV - it will run normally if you have registered with the April key
6. Return to settings and revert the month change back to the current date (if you don't several functions will fail to operate - for example youtube stops loading etc.)
7. Rip your disc, you should be fine.
