I did it yesterday and it still doesn't work.
To be honest, besides that - the application doesn't work properly, i tried to upload my project to the web server 4 times and it didn't work well. After all the files are uploaded, it gets into an infinite loop of 'prepare file..'
The bottom line, I couldn't upload my project to the web server with Cyberduck so in the end i did it with FileZilla.
I paid 25$ for something that doesn't work.
If you can't fix it then i would like to have a refund please.
