I have been a PersonalBrain (currently 3.02 Mar 1, 2004) user for many years, since the early 3.0 betas. I recently learned of the 4.0 upgrade, and downloaded the Free "Pro Trial" version with the intent to upgrade all the way to 4.0 Pro.
I have two large existing Brains, one with about 4,500 ideas, the other with about 8,400. The smaller one seems to have converted very smoothly, and seems to be correctly replicated. The problem I am having is with the larger one, and the conversion has created quite a mess of idea duplication, some ideas being replicated (along with all their linked subordinate and sibling/peer ideas) as often as three times.
The conversion (which I have run twice, each on a clean copy of my original), seems to do perfectly well until the program enters the indexing of weblinks phase. This brain has single webpages or graphics attached to at least half of all the 8,400 ideas. The first step of the weblink indexing program finds over 10,100 weblinks to index! (The first attempt found about 16,000 weblinks, corrected by fiddling with the root idea in the 3.02 brain, and eliminating one very high multi-parent relationship.)
The problem may have something to do with multi-parental links, as the duplications seem to occur in hierarchies below an idea that has two parents, and the icon displayed by ONE of the hierarchies changes to the [W] icon, whereas the other one of two duplicate hierarchies retain the old [e] icon from the original 3.02 brain.
Help! I cannot possibly correct this VERY technical scientific Brain by hand, and if I cannot get it to convert, I'll not be able to upgrade.
