ergData/PM5 v323 Interval problems

[bojam]

Since I updated from 320 to 323 my bikeErg PM5 has not been behaving properly when doing interval sessions.

I have set up both simple and complex interval sessions and both are affected by this bug. The session is set up normally and the first part is ok but when the 1st part has ended the message 'are you finished?' comes up on ergData, this is odd as I have not stopped pedalling as I do active rests.

Then the rest period ends and the timer counts down but no distance or any other unit appears to change. Only if I stop and wait does the display change, by which time it has spoilt my session.

How do I go back to V320 firmware?
