Cubik Studio

i bought cubikstudio.
i installed cubikupdater and ran it
waited for download and suddenly an error occured "Downloaded file is corrupted,Please retry later or contact Cubik support"
so I looked for the method to fix this and found i have to delete cubikstudio.exe and retry updater.
but i cant find cubikstudio.exe on my computer.
what should i do?

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.
