hashcat-gui v0.5.1

[mastercracker]

I have problem with 0.5.1
When i was select hccap file and select brute-force (WPA/WPA) command is:

cudaHashcat-plus64.exe --hash-type 2500 --attack-mode 3 C:\Users\qwerty\Desktop\9018_1346010557.hccap

show me this error:

Usage: /\cudaHashcat-plus.exe [options]... hash|hashfile|hccapfile [dictionary|mask|directory]...
Try --help for more help.

What is wrong?

This seems to often be the problem. You did not specify a mask. Besides that, you really did not post at the right place. How about "Support" and "OCLHashcat-plus"...
