I don't have Blockbase, only EQ7, and will not be upgrading in the near future. Had a look at the website and found these reviews from some who bought the original Blockbase, and the first one states that she had no issues in linking it up to EQ7.
Blockbase reviews.
Unfortunately, the reviewer is referring to the original BlockBase, which is apparently not
compatible with EQ8.
I used the originial with EQ7, and loved it, but I can't get it running on Windows 10.
