padawan, you used stripper??? then i understand. look here:
005996BA |. 8945 D4 MOV DWORD PTR SS:[EBP-2C],EAX ; | 005996BD |. C645 D8 0B MOV BYTE PTR SS:[EBP-28],0B ; | 005996C1 |. 8D55 D4 LEA EDX,DWORD PTR SS:[EBP-2C] ; | 005996C4 |. 33C9 XOR ECX,ECX ; | 005996C6 |. B8 74975900 MOV EAX,_PHPProc.00599774 ; |ASCII "Can't load language library: %s.lng" 005996CB |. E8 7016E7FF CALL _PHPProc.0040AD40 ; \_PHPProc.0040AD40 005996D0 |. 8B45 DC MOV EAX,DWORD PTR SS:[EBP-24] 005996D3 |. E8 A4B8E6FF CALL _PHPProc.00404F7C 005996D8 |. 8BD0 MOV EDX,EAX 005996DA |. B9 98975900 MOV ECX,_PHPProc.00599798 ; ASCII "Error!" 005996DF |. A1 D0735A00 MOV EAX,DWORD PTR DS:[5A73D0] 005996E4 |. 8B00 MOV EAX,DWORD PTR DS:[EAX] 005996E6 |. E8 9162EDFF CALL _PHPProc.0046F97C 005996EB |. E8 48B2E6FF CALL _PHPProc.00404938 005996F0 |> FF15 2C6F5A00 CALL DWORD PTR DS:[5A6F2C] if you use stripper, this DWORD will be 00598F3C. this means: program expired (this dword is set by aspr). you have to modify this offset to 00598E28 and all works perfect. 005996F6 |. A1 D0735A00 MOV EAX,DWORD PTR DS:[5A73D0] 005996FB |. 8B00 MOV EAX,DWORD PTR DS:[EAX] 005996FD |.

BA 05000000 MOV EDX,5 00599717 |. E8 D4B3E6FF CALL _PHPProc.00404AF0 0059971C \. C3 RETN 0059971D .^E9 0AADE6FF JMP _PHPProc.0040442C 00599722 .^EB EB JMP SHORT _PHPProc.0059970F MaRKuS TH-DJM / SnD TeaM PS: it doesn't use any APIs like you mentioned. but all the parameters (or lets say: DWORDS) for the program are set while ASProtect unpacks the target. so it is able to lead the code to other location (like here) where the program says: unregistered. so you can't find a way to crack it. but as you see, it is possible.
