Licensing new SFTDrive/ExpanDrive beta?

I downloaded the SFTPDrive beta (renamed to ExpanDrive) which does seem to cure the crashing problem that I and many others had, Great!

However, I don't see any way to apply my existing license to the beta, and the demo only has 8 days left. It's looking for a license file, but I only have a license code.

Will I be able to license the new version with an existing license, or will I need to purchase it again?

Thanks!
