Total newbie needing advice

If your .hccap file isn't in the same dir as hashcat, you'll have to put in the path, just like every other command line interface out there. Basic OS usage stuff you should learn.

[hashcat executable] -m 2500 -a 3 [path to where your HCCAP file is]/myfile.hccap ?l?l?l?l?l?l?l?l

or in your case, I think you should just copy it into your hashcat folder with the .exe and .bin files, etc.
