I just checked the dll files and they are ok. From the screenshot I would think that you copied the client plugin dll into the server plugin folder.The installer is OK, I think the attached DLL zip file contains a wrong file...
It shows as incompatible plugin in TV Server
I have the same problemCopied the dll's to the appropriate folders, restarted TvService and plugin was listed as incompatible.
As far as I could see your tv.log contains only errors / exceptions. Is this the right log file?I attached the tv.log showing the issue.
