Read Profile ACE6000

Hi
I want to read profile(without parse) of ACE6000 meter, I followed the example code in:
https://github.com/Gurux/Gurux.DLMS.cpp/blob/master/GuruxDLMSClientExam…
but i was not successful.
I wrote this code:

std::string value;
std::string str;
std::string ln;
std::vector<std::pair<CGXDLMSObject*, unsigned char> > list;
CGXDLMSObjectCollection Objects;
if ((ret = GetObjects(Objects)) != 0)
{
TRACE("Initialize Connection failed %s.\r\n", CGXDLMSConverter::GetErrorMessage(ret));
return 1;
}
// Read scalers and units from the device.
for(std::vector<CGXDLMSObject*>::iterator it = Objects.begin(); it != Objects.end(); ++it)
{
if ((*it)->GetObjectType() == DLMS_OBJECT_TYPE_REGISTER ||
(*it)->GetObjectType() == DLMS_OBJECT_TYPE_EXTENDED_REGISTER)
{
list.push_back(std::make_pair(*it, 3));
}
else if ((*it)->GetObjectType() == DLMS_OBJECT_TYPE_DEMAND_REGISTER)
{
list.push_back(std::make_pair(*it, 4));
}
}

if ((ret = ReadList(list)) != 0)
{
//If readlist is not supported read in old way.
for(std::vector<CGXDLMSObject*>::iterator it = Objects.begin(); it != Objects.end(); ++it)
{
if ((*it)->GetObjectType() == DLMS_OBJECT_TYPE_REGISTER ||
(*it)->GetObjectType() == DLMS_OBJECT_TYPE_EXTENDED_REGISTER)
{
(*it)->GetLogicalName(ln);
TRACE("%s\r\n", ln.c_str());
if ((ret = Read(*it, 3, value)) != 0)
{
TRACE("Err! Failed to read register: %s", CGXDLMSConverter::GetErrorMessage(ret));
//Continue reading.
continue;
}
}
else if ((*it)->GetObjectType() == DLMS_OBJECT_TYPE_DEMAND_REGISTER)
{
(*it)->GetLogicalName(ln);
TRACE("%s\r\n", ln.c_str());
if ((ret = Read(*it, 4, value)) != 0)
{
TRACE("Err! Failed to read demand register: %s", CGXDLMSConverter::GetErrorMessage(ret));
//Continue reading.
continue;
}
}
}
}

But i cant read the profile. can you help me where is my mistake?
Thanks
