Using Aircrack for Windows

Howdy everyone,

Can someone PLEASE help me how you can tell if an access point uses 64bit or 128 bit WEP? Also, What options can you use to crack wep faster. The two commands that I used were:
"C:\aircrack-ng-0.6.2-win\bin>aircrack-ng.exe -a 1 -q -n 128 -b 00:00:00:00:00:00:00 [my file].ivs" (I used the MAC address i got from netstumbler)
and
"C:\aircrack-ng-0.6.2-win\bin>aircrack-ng.exe -a 1 [my file].ivs"
but each I let run for 14 hours without success. Any one know a better way to do it using XP?

I'd appreciate any help. Thank you in advance.
