Custom ID Tag failure for V4

[gfrnd]

I had been using the Beta version of V4 and things were fine; when installed the final V4 (after uninstalling the beta) my custom ID tag no longer works; it is still in the tree but the contents are empty.
I went back to the sticky but the directions no longer seem to work as the regedit entry described does not exist; went through all references in the registry and couldn't find any reference to default user path.
Then I searched the system for the MediaDatabaseFields.txt file but only came with MediaDatabaseFieldsV3.txt as a file.
Is there something that I have done wrong?
running on WHS V11 but installed as a windows program since that was the approach I had previously used.

Thanks

Re: Custom ID Tag failure for V4

Oops, I found a solution; I had stored the location of the MediaDatabaseFields.txt file, found one tagged as V4 and pasted the custom tag text from the V3 file; restarted and re-built db and now everything is fine; sorry for jumping to quickly
