I am using SleepyHead Software since Oct. 2014 with several different CPAP devices by Resmed.
On a weekly base, I transer the complete data onthe memory card into SleepyHead and so I have a complete overview of my sleep parameters since then.
Today, I realized that I can access only to data starting by end of 2020.
Has anyone an idea what could has been happened?
BTW I have backups of the memory cards since 2014 on a weekly base, but it would be a lot of work to re-read all this data.
Thanks in advance
