S4 to S5, going back to S4, backup failed, downloaded, issues

[utb ghost]

Downloaded 5 having deleted 4.3.24.. too complex for now. Deleted, and downloaded 4 again .....

sequences hang up at start (first 0.1 second)

maybe a patch that is not in the download of my old software version?

yes I backed up but had restoration issues for some reason)

[Mr. P]

You can't convert sequences backwards if you already converted them from S4 to S5. You will have to install your previous version of S4 and use your backup sequences from S4.

[PhilMassey]

If you go backwards you should uninstall S5. It might help to delete the LOR folder in C:\Programfiles(x86)

Then  reinstall your S4.

There are no other files you will need.

As Mr P said you will need your original S4 sequences. Any changes you made in S5 will be lost.
