Okay, the Acronis software did load enough to show a 'technical support' link. I logged onto this page and it gave an option of re-downloading the software I purchased. (Thanks Acronis!!!)
I now have Acronis Disk Director Suite 10.0 running fine, and acomplished the merger of partitions by deleting the larger unused partition, then I clicked on 'expand free space' for the partition my operating system is on (drive C in this case). Acronis allocated the deleted partition space to this partition and I now have 1 partition , with 232.88 GB.
So I got what I wanted mostly, but what happened to the other 17.12 GB of drive space?
