Been trying to restore 19.3.9 to home computer. Got this error

Unhandled exception: Field not found: 'DataConnectionBase.DataConnection.DataReaderNullTimeoutSeconds'.

Any help would be appreciated.

Do you compile your own Open Dental?

No, I do not.
I did upgrade from 19.2.35 to 19.3.9 at home and the office . Discovered 19.3.9 was too buggy. Decided to go back and install 19.2.35 or one of those versions, at home. That is when the error occurs.
We still have 19.3.9 at the office.

Judging by the error you're getting, it looks like your home is half on 19.3 and half on 19.2. I would reinstall Open Dental on your home computer.

Tried that twice. Deleted Opendental data but not OD Images. No luck. I will delete everything, do a clean install and go from there.
Very frustrating.

After you reinstall, can you right-click on these two files, select "Properties", and tell me the version numbers?
C:\Program Files (x86)\Open Dental\DataConnectionBase.dll
C:\Program Files (x86)\Open Dental\OpenDental.exe

C:\Program Files (x86)\Open Dental\DataConnectionBase.dll V 1.0.0.0

C:\Program Files (x86)\Open Dental\OpenDental.exe V19.3.15.0

Should I just copy the .dll file from office to home?

Cmcgehee,

Just copied a new version of C:\Program Files (x86)\Open Dental\DataConnectionBase.dll to my home computer and it worked like a charm. Back in business.
Thanks for the input.
