Corel took over B4 and marketed that for a while. I upgraded and the upgrade left B4 on my drive as well as B5. It didn't overwrite, it installed an entirely new directory. Since you didn't start out with B4, then I stand corrected. I thought you were trying to bring your B4 object presets into B5. You can bring a B4 file into B5. On open file, use the pull down box to highlight b4 files. The program does that just fine. As for legalities, if you own the B4 (by creating it on a friend's puter, or by acquiring it appropriately ... gift ... purchase ... etc) then I would think you can bring it in and convert it to a B5 just fine. Clay? You got any legalese insight here?
