Hello I’m having an issue after updating from 2021 to 2021.1 the same files I was working on before without problem are now giving me the prompt:
Hello @blbooker3966
Depending on how the update was performed, your previous config may have been lost. So if your preferences were set before to allow your system to work with undo histories of that size, you will have to again set those values, and store the config (preferences > Config> Store config). The prompt directs you to which preferences you’ll need to change.
If the values are the same, and the file size is the same, and the same file opens without issue in the previous version but not in 2021.1, then this issue will have to be referred to Pixologic Support.
Got the solution! The Reserved Undo Memory slider in the preferences was set to the max instead of 0. Once a set it to 0 everything worked and the undo history recorded everything.
