Subject: red repetition blocks in SleepChart

Question:

Today morning, all the red blocks marking the times of learning in SuperMemo are gone from SleepChart. Yesterday night I had a crash and SuperMemo was aborted without closing. How can I recorder that data? It is very important information for me

Answer:

• File : Repair collection with Repetition history checked will mark all prior repetitions in the timeline (this will not restore blocks made by prior edits or browsing)
• in your most recent backup, find file \stats\time.tim and put it in your current version of the collection (this will restore all data up to the date of the backup)
