Hmmm ....
Don't know why you needed to rename the page and the links.
Could you append your "_ProfitUI_StandardSearches.txt"?
Mine says <Page Name="StdSrch" ...
As does the original one from 3.4.8b.
Looks like yours says <Page Name="ProfitUI_StdSrch" ...
This could be, that you changed the links in an old version and the name of the page of the searchfile was changed since then.
