746-2850 
EDIT: Yeaps, you don't use GetVolumeID, BUT you do use 3-4 timers. Hence my serial will change on every run How to fix - send the timers in a long "sleep" (999999999...9 should do)

Fixing, as you say:
| Quote: | | 450B41 E8 8AEFFDFF CALL 1.0042FAD0 |
to
| Quote: | | 450B41 E8 00000000 CALL 1.00450B46 // a.k.a. NOP |
That's about it. After patching, use 746-9999 to pass the "test"

what?
password is being held at local.2
then being moved to edx.
if u nop 450b41 password isnt generated at all.
making randomaly generated passwords is stupid cause it force the high level crackers to use low level techniques. (i.e.nop)

| Trust me and test it Fire up Olly and set a break there. Once you type in the pass, and Olly breaks, just move to next line (use Ctrl+* to set origin to next line below the call). Have fun...

| He's using 4 timers. 2 timers: 1 for "746" box, 1 for "9999" box; the other 2 timers randomize the "9999" value in last box Just do it my way Oh, and it's a CrackMe, hence patching is allowed o_O Or am I wrong? Be it as it may, my first post showed I can get the pass without patching. So, I think I've fucked it every way around xD
