If you want to update Tripwire, You have to have the latest stable version of glider wich can be found at : http://www.mmoglider.com/Release/178/GliderDeploy.exe
And Do you have Tripwire enabled? If not do it. It should remove your issue
Note: Sometimes tripwire is a tard and starts to scream for no reason, just restart your computer and start glider again.
