Trying to recover my UI

[horse21]

So, something happened that has caused some issues. I'm not sure if it was running WoW in linux through wine, or installing the auctioneer mod.

When I log in, none of my RDX frames show up. The RDX main menu backdrop and button names display, but not the buttons. The floating RDX circle button also displays. When I /reloadui, the RDX main menu buttons come up, but none of my frames. The only error that comes up is when I mouseover something, something about 'attempt to index upvalue 'bkdtmp' (a nil value)' in GameTooltip.lua, though I assume the game tooltip wouldn't drop my UI.

It seems like all of the RDX main menu buttons work after I reload the UI. However, the only entries in the Repository Object Browser are:
WoWRDX
default
desktops
scripts

WoWRDX has almost nothing in it (Party_fset only)
default seems like it may have everything
desktops is empty
scripts is empty (though I believe it was before this happened anyhow)

So, all of the default themes, as well as my own package are no longer there. When I try and click on the 'UI->Themes' in the RDX main menu, the Themes dropdown does not show up.

What may have caused this? Most importantly, what file would my UI be located in, in case I need to reinstall? I hit the Backup Packages for my package a couple times, but I don't see anything in the Addons/RDX_recovery/RDX_recovery.lua file

Thanks for the help!
