Dear Hopsan developers, Sorry for the confusion. I used the latest 2.22.0 to open an existing hmf file. It failed sith the error message shown below: [09:55:19] Warning: I found old log data on disk and will not remove it because another instance of Hopsan is running. I even reboot my machine to make sure this is the only active hopsan job. However, the issue persists. Could you please let me know what is going on, am I missing something? Thanks. BTW, the last version which can open this hmf file is 2.18. Your advice will be highly appreciated.

Hi, I don't think the warning is related to the crash. The old log data will not affect the current instance of Hopsan; removing it is only for saving disk space. I would guess there is something wrong with the hmf file. It could also be that the model actually opens correctly, but the components are not centered in the view - the workspace size was increased lately, which might have this affect on old models. Can you try to zoom out and search the entire workspace for your model (assuming of course there is a workspace)?

Hi, thanks a lot. You are correct, the files actually was successfully loaded. I just have to search all over to find it. Appreciate your help.
