hello,

i have got problem with safedisc 2.90. i am using ollydbg and ida on windows xp (on vmware because i am using linux as a main OS), i have read peex's tut and ArthaXerX's info.
i patch main.exe, and the files are always extracting to one directory and they are not overwritten. i have patch antydebbug functions in ~df394b.tmp file (IsDebuggerPressent, ZwQueryInformationProcess, checking for "CC" bytes). program don't show messagebox with request to close debugger. i have got original program so didnt do anything in CdaSdTest. my problem appears after splash screen disappers... main program calls kernel32.WaitForSingleObject with time argument = infinitive and it stop in it. i dont know whats going on there... i tried to patch this too, but after this function, program install SEH and jump to junk code of unpacked original program code (i know that because i am recognize ascii strings). i have checked SEH function but its normal messagebox with information about unhandled exception. any hints? how can i find OEP, or which antycracking function i should look?

PS. sorry for my poor language

check through riscs code for unsafedisc, it shows how to find the oep (and it hasnt changed in quite some time), and use the search button!
