For winIDEA version 9.21.41 and newer SFR database corruption is detected and SFRs are recreated automatically.
When SFR database is recreated, custom SFRs are deleted.
For other winIDEA versions go here:
First check if the folder for SFR database location exist on your PC:
1. Open Tools menu / Options / SFRs.
2. If the SFR database does exist (indicated in the Default field), then press Recreate database.

Command Recreate database is located in Debug menu / Debug Options / SFRs.
Manually recreate the database:1. Press Open in Debug menu / Debug Options / SFRs. This will open the folder which contains the SFR database.
2. Close winIDEA.
3. In the opened folder, go up one level and delete the SFR folder.
4. Open winIDEA. The SFR database will be recreated.
Depending on your PC it might take a couple of minutes.
