Loading data gets stuck

[Lnicholls2000|NewGmodServer!]

All of a sudden, when I open the XGUI, almost all of the data loads, but gets stuck at 95.24%. So anything like ban data and URM restrictions data won't show in the XGUI.
This is what it looks like: http://i.imgur.com/ZGoIOLN.jpg

My ULib/ULX versions:
ULib v2.60
ULX v3.70

Game mode(s) I am having this problem on:
Sandbox

Lua errors shown in console:

Code: [Select]

[ERROR] lua/includes/extensions/net.lua:182: net.ReadType: Couldn't read type 148

Okay, so it seems that if I'm doing things like restricting some entities from ranks, the XGUI refreshes, and will sometimes fully load, which is a good sign at least.

First thing you should do is update your ULX and ULib versions to the latest.

Is there a way of keeping all of the data like restrictions, ranks and permissions?

Yes. These are stored outside of the addon folders, and will remain as-is after an upgrade.
This may not be your issue, though. I believe I've seen the "couldn't read type" issue when too many net messages are registered/sent. However, give an upgrade a try anyway.
