Ok ...A lesson learned here tonight and a happy ending too.
Something Dennis said got me thinking so I decided to do an experiment. The way he got to 4.2v3 VS the way I did.
So first my way.
To be sure I had no rogue LSCP files I deleted the entire GigaLibrary folder and the the LSCP file from the Preset folder. Extracted the RAR to get back a fresh GigaLibrary folder, and copied the LSCP file from there into the Preset folder.
Next I went to user/mediastation and extracted OS 4.2v3. When asked if I wished to overwrite all the files I selected Yes.
Rebooted and no success. The problems remained.
So next I did what Dennis did. I deleted the current folder rather than allowing the 4.2v3 RAR to overwrite it.
Rebooted and ..... success
So what ya think of that. Overwriting the current folder did not work ( and I done 3 times in total) yet the second I deleted it and replace it like Dennis did, success.
Ho well, a lesson learned. Don't overwrite files. Delete them first if you want to replace them.
So thanks Dom, Dennis & AFG.
