I believe I bought iTube for windows and Mac so long ago, and I loved the app. Recently, I have had issues and it seems to not have support and may have been sold. The response from the company has been this:

“Please be aware that iTube Studio is now an outdated product that we no longer maintain, and as a result, we are unable to provide support for any technical issues arising from it. We apologize for any inconvenience this may cause you.”

It even looks like this.
