Hey foff44,
To fix the text-only issue, the easiest thing might be to open Silo, go to File > Reveal Preferences Folder, and then delete the entire “Preferences” folder you see there. (If you have custom settings saved in there, you should pull them out first, of course, and have them somewhere safe to put back in). Then close and reopen Silo (2.5.04) and it will automatically recreate that folder give you the new UI set.
Also as a note for anyone else reading along – note that the .sip file for the UI is important and tells Silo where to get the images from. A good setup is to have the .sip file next to a folder containing the images for that set. So, for example:
Preferences
– Presets
---- Button Settings
 ------ OrangeUI.sip
 ------ OrangeUI (folder)
This will give you “OrangeUI” as an option in the Button Settings Presets dropdown, and also not overwrite any existing Button Settings images (by keeping each UI in its own folder within Button Settings).
Then note (depending on the .sip file you get) that you may need to open that .sip file in a text editor and do a full search-and-replace-all on the filepath so it goes to the right place. In the OrangeUI setup I noticed that the SIP file had “/Applications/Silo 2.1 Beta 6-20-2008/Interfaces/OrangeTabs/[imagename]” as part of the filepath – that location doesn’t exist on my system, so all of the images showed up blank. With the setup above, you can change that to simply “OrangeUI/[imagename]” (note no / at the beginning), which will also for universal sharing as long as the folder relationship above is maintained.
If you’d like the edited SIP file/imageset, I put that here: http://nevercenter.com/silo/support/downloads/OrangeUI.zip
Nice work, everyone, being so helpful! Thanks for letting me put my 2 cents in.
