There is no file called program.lst anywhere on my drives. F5 only opens the playlist in FL studio and does nothing in the standalone Rapture version.

Ensure that you are focussed on (click within) the Browser pop-up window when pressing F5. If that doesn't work then there's something amiss with you installation or a conflict with other programs/setup that has commandeered the F5 key.
 
This thread is far too wieldy for use as a Sticky. If that were to be done I suggest a purpose built entry with clear topic and content. But it is in the manual (bonus points).

Hello guys. Is there any possibility to get back my old Rapture's sounds if I don't have an installer (f.e. Craig Anderton's Electronic Guitars"). I asked Cakewalk to bring them back to my account cause I probably downloaded them as freebies. So I'm wondering which file (F5 doesn't work of course in this case - I copied all sounds to a new installation directory) keeps information about installed expansions to "help it see" my sounds?
 
Edit: Ok, there's no file, just copy sounds to ProgramData\Cakewalk\Rapture\Programs and... F5 . Hope this helps some people.
 
 
Edit 2: Damn it. Some sounds just give this:
 
File c:\program files\cakewalk\rapture\multisamples\technoguitars\5ths_distortion\5ths_dist_e1.wav not found or couldn't be loaded.
File c:\program files\cakewalk\rapture\multisamples\technoguitars\5ths_distortion\5ths_dist_a1.wav not found or couldn't be loaded.
File c:\program files\cakewalk\rapture\multisamples\technoguitars\5ths_distortion\5ths_dist_d2.wav not found or couldn't be loaded.
File c:\program files\cakewalk\rapture\multisamples\technoguitars\5ths_distortion\5ths_dist_g2.wav not found or couldn't be loaded.
 
:/  Files are in place, they can be heard by just playing them in windows..
 
Ok, last edit. Files were corrupted. Maybe someone will take advantage of my "way to success" :)
