This almost makes no sense, could be corrupted files? bad drive?
-so errors point exactly where clothing is, but on scene load it appears it's not there? (if you get "invalid load path or params" you have them in wrong folder)
-since they are local (custom) stuff (probably read-only),
what happens if you equip
Clothing Creator and than
Customize>Load Existing>search for .vam of missing items?
can you load them or can't even see .vam files?
-doubt it's something permission related (write protected folder), you are only reading stuff
in any case, what
vam version you use and is your client located inside
protected folder (example: c:/program files)
-is there any way you can get at least one fresh copy of missing clothing? backup? (to compare file size in case something is corrupted?)
-last resort (since i am out of ideas) get 2nd vam client (19GB), but download it on c:desktop (or on different drive, if you have)
copy some of missing clothes inside new client see if it loads
