Moving FF3 to new system...

I just bought a new Win 7 system, and have had a hellish time trying to move FF3 from older Win 7 system. I tried to do it as follows:

1) Installed FF3 on new system

2) Copied entire contents of C:\Users\MyAccount\AppData\Roaming\Filter Forge 3\ to USB key.

3) Copied info from USB key to equivalent C:\Users\.. .\ folder on new system

4) Compared both folder contents which matched identically

All my filters survived the move, but the index no longer works. Even when I search by exact filter name, I either get totally wrong hits or no hits at all.

I think I've found the convergence point between Windows 7's dreadful user interface (just wait for Metro on the desktop!) and FF3's anemic filter browser.

Thanks in advance to anyone who can tell me how to rebuild the filter index.

Delete Librarystructure.xml and Library.xml, these files are interdependent.
Note that the next Filter Forge start is going to be slow because it re-indexes all your filters.
