DownloadStudio extension reporting as corrupt with Chrome V63.

I have successfully been using the DownloadStudio extension with Chrome on a Windows 10 x64 PC without any problems until I recently updated Chrome to V63. It now reports that the extension may be corrupt. I have tried removing the extension and then adding it back again but with no success.
Any ideas how to solve this problem?
Thanks
Chris
