Currently running Kiwi CatTools 3.4 (Freeware)
Debug: Attempting open of database: C:\Program Files\CatTools3\KiwiDB-CatTools.kdb
everything seems to be working but that info shows up in that Info Log tab. I have attached a screenshot.
That is not a error message.
The messages with Level 4 type are just debug purpose.
You can ignore those.
