"Upload is running" on closing my game

No, but we have found a way to fix that by changing the user permissions on the log file that keeps getting stuck in "uploading" mode when it really isn't doing anything. The file is in your TS3 user game folder in Documents and is called Sims3Logs.xml (it may show up as just Sims3Logs if you have Windows set to disable extensions). Right-click, Properties, Security, and deny the file Read access at the user, SYSTEM, and admin levels.

This hit most of us on Steam (only when the Launcher is used though, it doesn't have to be) and many others on Patch 1.67 beginning a couple of months ago. Some small change EA made on their end apparently did not take 1.67 players into account.

@puzzlezaddict - Do you have a link to the discussion about this on AHQ handy in case it's needed or any corrections to offer in case I'm not remembering the required access rights change correctly?

Edit: Ah, found it.

I bypass the launcher when opening my game, but when I use it to install or uninstall something, I get that same message. It shouldn't be uploading anything when all I did was install the latest version of the world I'm working on in CAW, especially when the launcher isn't even logged in. I'm glad there's a solution to it, so I can stop closing the launcher with the Windows task manager every time I use it.

Thank you @igazor ! :)
