SnowdreamDavidTheWinI hope you're monitoring this because I've had one hell of a confusing night. First, Lawena was telling me it couldn't replace the custom folder, so I checked the permissions on it, it was read only so I turned that off. Same error. Turns out I have a fairly common bug with Windows where it sets read only permissions on folders and nothing can change it. In the end, I replaced the custom and cfg folders manually with the vpk's and HUD I wanted, but there was still the problem of Lawena trying to replace the newly filled custom/cfg folders again. I suppose this is where it becomes LWRT relevant. Before I found the read-only issue, I tried resetting the recording settings I was using and I found that if I didn't save the changes to the settings then I could launch TF2 without the "cannot replace custom" error but I wouldn't have any LWRT configs/files. After replacing the cfg/custom folders manually, the tool works like normal.
I got "cannot replace custom"
Restarted steam
Tool worked
...
maybe I'll try that
