Prins dlm "tank empty" error

Hello, I have a BMW 320i 2010 n43b20 with a Prins Direct Liquimax kit (I do not know which generation, but I think it's the first one). Recently I experienced some problems, it does not switch to gas anymore. On the tester begins the process of switching from gasoline to LPG, but when it comes to approx. 10% jumps immediately to 95% and then drops to 0%. In addition, the Tanker section will display Tank Empty in the Tester software. The tank is obviously not empty. Nobody from Romania knows how to fix it or which component needs to be replaced. Some say it's the boost pump, others say it's the LPG pump driver ... I'd be happy if any of you could help me. Many Thanks!!!
