So as an update, since I just got home from work. I have no idea what changed, perhaps it was me turning my pc off and then on. It works now. RAGE still says that my GTA 5 is pirated, though it isn't. But I it's working as it should, it seems. Thank you for trying to help anyways though.
Sorry for the long reply time, had to get some sleep before work.
I'm using the default Windows 10 antivirus. I haven't been Windows 10 long so I'm not super familiar with it yet, but I think its called windows security.
The title really says it all. I bought my copy of GTAV on steam a few years ago and have finally started to try modding. LSPDFR looks really interesting and I thought I'd start there, but I can't seem to figure out why RAGE thinks my GTAV is pirated. I've reinstalled both GTA and RAGE to no avail.
Thanks in advance, sorry if this is an issue that's been posted before. I actually made an account here just to get some help.
