RainbowCrack: poor success rate

I've had a difficult time trying to find online resources to crack MD5's, and so I've turned to attempting to get my own hands dirty. I followed the rainbowcrack tutorial's example, but changed it to MD5 instead of lm. Here are the commands I used to generate the tables:

rtgen md5 alpha-numeric 4 8 0 2100 8000000 all
rtgen md5 alpha-numeric 4 8 1 2100 8000000 all
rtgen md5 alpha-numeric 4 8 2 2100 8000000 all
rtgen md5 alpha-numeric 4 8 3 2100 8000000 all
rtgen md5 alpha-numeric 4 8 4 2100 8000000 all
rtgen md5 alpha-numeric 4 8 5 2100 8000000 all

I've tried to crack a bunch of MD5's using the generated tables, but have had terrible success rates. I have a very faint understanding of how the chain length and chain count variables affect the results. Can anyone see where I might be going wrong?

Thanks.

Generating rainbow tables is very time consuming process.
I suggest to download allready generated tables:

I have right now 5 different sets of MD5 rainbow tables and they are working perfectly so far Smile

Yea. It took a lot of processor power to generate the ones that I did. Thanks for the pointer.
