Please help. Stopped working

Hello

Last time i wrote this plugin does not work proberly. Then after a long time a reaction cam and said update with the latest update. I did that. Then it looked better and different and it still did not work. Then i again wrote a support. A new update cam really quick of this plugin.
Then it really worked well. And it worked amazingly beautifull.
Then another update came today and it doe not work anymore.

Just to make sure and share my steps i did for minutes ago

1. I deleted your plugin.
2. Then i deactivated the other plguins.
3. I deleted all my cookies.
4. Then i installed the latest version of your again.
5. And i still keep getting the 404 error page. This was not before the last update.

What can be done to fix this? I am willing to pay if needed because it is a real great plugin if it works.

Thank you in advanced!

What can be wrong then please?
