Be sure you have a copy of your old, existing BB and RB folders that you've been using on your old computer. Don't make ANY changes on them. Keep those.

Go to the STYLES folder on the newly installed BB folder tree on your new computer. Highlight the STYLES folder, right click COPY and then highlight the BB folder and click PASTE. That should give you a STYLES- Copy folder. Now your newly installed STYLES folder is backed up as-is. Rename the STYLES folder on that new computer as STYLES-NEW_INSTALL.

Go to the old BB folder on the old computer and highlight STYLES and then copy -NOT MOVE- that folder to a flash drive or something and then go to the new computer and PASTE that STYLES folder into your new computer's BB folder. You might have to do something different if not via flash drive or whatever, but the idea is to get your STYLES folder over to your new computer inside the BB folder.

When done, run BIAB on the new computer and do a rebuild and see if you have success. IT MIGHT TAKE SEVERAL REBUILDS. Mine did.

If no success there, you might want to go to the support section of the website and your purchased files should be there available for download and reinstall. You would probably want to use the automated install program. If you do go that route, first rename your existing BB folder on your new computer to something like BB-NO_GOOD or something before you begin so that you're guaranteed to have a fresh install. After you have success you can delete the BB-NO_GOOD folder whenever you're happy. PG might have other ideas, but the above worked for me when I had to do some juggling around with upgrades and different HD's. YMMV, but just throwing out ideas hoping something helps.
