Need help with fixing error code 3. Please

[Millenium20]

Hello everyone! Im a student and very new in LabVIEW. I created an imitating model in LabView for my project at the university but it doesn't open correctly. Down below you can see my problem. The interesting thing that i can open my model in LabVIEW 2019 without any mistakes and it works. But for my project my model must be in LabVIEW 2009. I really dont know how to solve this mistake because just like i said im very new in LabVIEW. I hope that someone can help me with this mistake.

There are 10 years between LV2009 and LV2019, you cannot expect compatibility between both when downconverting from LV2019…

Recreate your VI from scratch, but start with LV2009!

There are two ways to ensure correct behaviour: either work with LV2009 or work with LV2019 - but don't mix using them!

You don't give sufficient information for us to troubleshoot. Did you try to open the 2019 VI in 2009 or did you down-convert it first to 2009? ("menu..file..save for previous").

Do you use many new features that are not available in 2009?
