Recommendations for alternative to OneDrive for Windows10?

I absolutely loved OneDrive within Windows10 and Opus's support thereof. Unfortunately, it looks like the initial release of Windows10 will not support OneDrive. I say this because the latest version of the Windows 10 beta just shows a cryptic code when I click on the OneDrive icon. To me, that's like releasing a new car model without wheels. So, I'm desperately looking for a cloud replacement for OneDrive that works nicely with Opus. Any recommendations?

Onedrive worked Ok for me in build 10166
Have just installed the latest build 10240 and onedrive is working fine in Dopus
I also have dropbox and google drive and they work Ok with Dopus.

Onedrive is working perfectly for me in build 10240.
