That's all good. Looks like you've successfully upgraded your galleries to SimpleViewer 2.1 (the latest version).
Now for svManager:
svManager version: 1.71 (I upgraded by...
Could you just check that svManager version number again please. Support for SimpleViewer 2.1 was added in svManager version 1.7.1 build 100923, so if that's what you got then that's fine. If it's one release earlier than that 126.96.36.199 build 100904 then you should upgrade svManager again.
The location of the simpleviewer.swf file changed in SimpleViewer 2.1. It's now in yourgalleryfolder/svcore/swf/simpleviewer.swf
Changing the simpleviewer.swf file from Standard to Pro should get rid of the link in existing galleries. You can also upgrade existing galleries using svBuilder.
The location of the svManager master file used to create new galleries changed as well. Since svManager 1.7.1 it's in svmanager/plugins/simpleviewer2/sv2master/svcore/swf/simpleviewer.swf
Changing the master simpleviewer.swf file from Standard to Pro should get rid of the link in new galleries created by svManager.
And (I always say this) take a backup first.
Hope this helps. I'll try to make things a bit clearer in the svManager user manual.
