Out of seemingly nowhere, having changed nothing between the last time I played LSPDFR and when the error started occurring, I'm experiencing an odd error whenever I try to go on duty.

Whether I use ForceDuty or try to go on duty at any station, the error is thrown and I only lose one plugin.

It seems that there's an issue with Ultimate Backup, however I've already uninstalled and reinstalled it and all of the XML files that were related to it.

Given the relatively vague log data I got it seems as if there's a misplaced character somewhere, but going off of the Line and Column data, I couldn't find anything.

Any help would be much appreciated.

RagePluginHook.log

Solved! Found out that for some reason when opening the file with 7zip, no matter what I did, whenever I moved it something would change and the file would no longer work. 

Even after deleting the xml file it seems it wanted to do this any time I tried moving it with 7zip, so when I used WinRAR it worked flawlessly.
 

Long story short, try WinRAR, I guess?
