Cubik Studio

I run CubikUpdater.exe but got error every time in the downloading process.
It seems that my Internet connection to the downloading sever is bad and I can hardly connect to it. Can I get an offline installer or is there any other way to solve the connection issue？

Generally just deleting all the files from the folder where the Updater is located, re-downloading the updater from the website, and trying again will fix the issue.
