Since getting GPO about 3 weeks ago I experienced a major computer crash. Mother board, hard drives, it's been a nightmare. I am now back up (I hope) and trying to restore everything. I reinstalled GPO then got the Studio update (after uninstalling the old one) and now when I try to load an instrument or orchestra it says it cannot locate that instrument. I looked in the GPO Library and the files appear to be there but Studio can't locate them. Help!
Click on the options panel of the Kontakt Player and in there is a directory where Kontakt 'thinks' the GPO library is. Just click the button beside it, manually search and find the GPO library folder and then click Save or OK or whatever (can't remember all the tiny steps, sorry.)
That should do it. I take it you installed the GPO library somewhere other than the default location?
