Sorry about the troubles. It seems LOGbinder is not able to access audit data from the site collection for some reason.
You mentioned that you set account permission, but just confirming that both the user running LOGbinder and the LOGbinder service account are SharePoint farm administrators and the LOGbinder service account it a site collection administrator on the site collection in question.
Could you please turn on diagnostic logging? Go to File / Options, select Level 1 logging. Then restart the service. After the error message comes up again, go to the "C:\ProgramData\LOGbinder SP" folder, compress and send to me in a private message all *.log files. You can sanitize the logs as necessary.
