What is your latest post supposed to tell the reader? Did you ask the developer if the plugin is 1.4.x compatible?
Or just install and actually try it!
Should you see errors, ask the developer!

No I did not ask the developer.
I was just wondering is there is a compatible version for this plugin because I found the above compatibility notes in the plugin website
