All plugins that use RbxUtility and/or RbxGui are failing

Hi! For the past two weeks, a LOT of people have been reporting that none of their plugins are working. Usually, when asked for log data, there is one thing in common between the output of all these failing plugins: they error when trying to use RbxUtility or RbxGui.

Here’s the log data of one user (of many) whose plugins are failing because of the same error:

If you look on the forums, you’ll find plenty of similar ones. Have libraries been phased out?

TL;DR: It appears that LoadLibrary has been returning nil for Studio plugins on some users’ machines for the past week or so.

Does this repro for everybody or just for some people?

We have a problem with some Studio installations (http://developer.roblox.com/forum/studio-bug-reports/8649-starterscript-doesn-t-load) that would also apply to libraries. We’ll try to patch it on Thursday, in the meantime doing a complete uninstall (by deleting C:\Users\andreas\AppData\Local\Roblox\Versions folder) should help.

It only happens to some users, and thanks for the info!
