To resolve this, reload your project using ADU Client > 122.0.1. > Your project was automatically saved during the upgrade and can be found at: > > ```auto > C:\Users\\Documents\ADU\\yyyymmdd_hhmm_ss_FIRMWARE_UPGRADE.adu > > ``` **Download the update here:** [https://www.ecumaster.com/tv](https://www.ecumaster.com/tv) Additionally, a new how-to document covering the setup of the Gear Calculator introduced in 122.0 is now available: [https://ecumaster.com/files/ADU/HowTo/How\_to\_Configure\_Gear\_Calculator\_in\_ADU.pdf](https://ecumaster.com/files/ADU/HowTo/How_to_Configure_Gear_Calculator_in_ADU.pdf) Sincerely, **The Ecumaster Team** ![adu_community](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/2/2651425150df40b7c09e6e11f20bc9b714ddc407.png) ---

I just identified that I have this issue and appear that some of my CAN exports are corrupted. At the same time, I am not able to connect to my ADU to make any changes. Trying to identify I cannot connect. It shows “Disconnected” vs Offline when nothing plugged in. I can see lots of data in Lite Client, but not individual modules. ---

I’m not sure if I understand what is your current issue and what you have done so far. More details would be helpful. 1. Can’t you connect to ADU anymore? 2. From which firmware version to which version did you upgrade? 3. Could you share your project file from before the upgrade and the one with the “corrupted” CAN Bus exports? You can share them here or via email: [maciej.fudala@ecumaster.com](mailto:maciej.fudala@ecumaster.com) 4. > [@325racer](#): > > It shows “Disconnected” vs Offline when nothing plugged in. I can see lots of data in Lite Client, but not individual modules. Did you have both ADU client and Light client running at the same time? ---

Further investigation, I now don’t believe my file was corrupted, but having some sort of CANBus problem which is not allowing me to connect to the ADU or PMU. The issues that caused me to start looking at the PMU seem to have gone away and everything is functioning correctly at the moment, so I won’t spend much more time on this at the moment. We’re at the track at the moment, so as long as stuff is working, I’m OK for now.
