Please start with creating a backup: Administration ‣ Databases ‣ Backup. Next, run Check Data from here. If successful, this will clean up any database corruption that may generate issued with recordings. I have not received reports like this otherwise, so I assume it is specific to your configurat...

Good to hear!

I still have a v1.2.6 firmware file available here. It is the firmware version that introduced 4/5 Hz sampling and the one that has been distributed by Dual through the (now broken) link available here on the forum. In case you are adventurous, drop me a mail with "please send Dual XGPS 1.26 firmwar...

You did everything correct, but LapTimer didn't. I just tested your scenario and found there is an issue with expression parameters > H. This means AC in the "=AC-40" formula doesn't work for v22.1.3. I will add a fix for the next bug fix release v22.1.4, but want to ask for some help to make sure i...

Please make sure you have the small switch in the appropriate position. There is an iOS and a non iOS setting. If I remember right, Dual had a special firmware version to allow high (i.e. 4 or 5 Hz depending on the hardware revision) rate. Please search the forum on Dual firmware, we had a link to t...

I assume you mean you purged laps recorded for the VIR track? In case you have not created an external backup you can restore (Administration ‣ Database ‣ Backup), you can check if LapTimer has created some system backup due to some issue. This system backups can be restored too. Before doing this, ...

I had a look into all your screenshots again. Especially the one showing the Video Details with all the Lap links is making clear the relation between laps / recordings and video where not setup correctly. I assume you applied multiple operations on the relation (like overlaying or Re-Linking), so i...

Try renaming the video file to something more standard first (no spaces, only one dot to separate the extension). I have worked on issues like this for v22, but there may still be some problems around. In case this doesn't help, it is probably an issue with the encoder used by the video editor... Ei...

Technically, you have a Petrolhead edition. That's because you bought this edition initially. When upgrading an app (like you did), it is still the app you had but with additional features enabled. Or the other way around: all LapTimer editions come with the same functionality. But depending on thei...
