Dataflash log download error - ACv3.5

Tried to download dataflash logs today after going to ACv3.5 and now everytime I get this error:

Getting list of log files…
Error:System.TimeoutException: Timeout on read - GetLogEntry
at MissionPlanner.MAVLinkInterface.GetLogEntry(UInt16 startno, UInt16 endno)
at MissionPlanner.MAVLinkInterface.GetLogList()
at MissionPlanner.Log.LogDownloadMavLink.b__12_0()

Any ideas or should I post an issue on the list?

Took the SD card out and all the new logs are like this:


whereas the older logs (v3.4.x) are like this:


and LASTLOG.TXT contains “216”

Edit: Not sure if this makes a difference as changing the file 00000216.BIN to 216.BIN still gives the error.
