If the delete command wasn't working, you have the vault path set wrong, most likely. Are you remembering to do a full recompile after you edit the path? Without that it'll still be using the old path. Please post a leto log of a failed deletion attempt using the SIMTools command - you can find the nwnx_leto.txt log in your logs.0 folder.
I put the newer dll files in the folder and it works now. I didnt even think to check that log file. Thanks for your help. If I remember right I had to use a few different dlls for the 1.69 update. I cant remember what ones though. I dont go messin with it if it works.
