I'm not finding "cPrCGunsli" as an id in the data files, so I'm assuming you've got some custom content you were working on, and HL got closed with a compilation error in the files. What I would do is pull that user file out of the folder and stick it on the desktop or something, load HL, then put that file back in the folder and open it in the editor to fix the id of skCrafGuns.
