I am trying to crack a program which is protected by Sentinel LM v7.1.1.It use lsapiw32.dll.I put bpx on VLSrequestExt and found featurename,version,units required.It breaks two times however version and units required is always zero.Are they zero or they changed this function ?

Also there is no exported function "computeVendorCode".I have also tired to apply signature to this dll file but still I cant find vendorcode.
