Default crash after patching flexlm-protected target

Hello

I found encryption seed using flexlm seed-extraction manual.
and applied ECC patch to vendor daemon.
when I run application, vendor daemon displays that feature is out. but application doesn't work.

so I tried to patch any application file, but then application crash.
is this due to my wrong license generation or some other
protection of integrity check?
if there is integrity check, let me know some references please.

thanks

Here is link.
http://depositfiles.com/files/shqaqa7ai

I zipped my seed, sample lic, and lm_core.dll too.
if I modify lm_core dll or any file that uses this, it crashes.
problem is in calling edx because edx is invalid address after patch.

.text:06F11720 call ds:GetLm
.text:06F11726 mov edx, [eax+10h]
.text:06F11729 lea ecx, [esp+90h+var_5C]
.text:06F1172D push ecx
.text:06F1172E push offset unk_6F1A010
.text:06F11733 call edx

thank you.
