GameCore 3.17 compiling problems

[killmeplease]

I have Visual Studio 2008 installed.
i'm new to modding and c++ (i write c# code at work) and need an advise.

after i loaded CvGameCoreDLL.vcproj in VS2008 and attempted to build it, an error occured: "'iI' : undeclared identifier" at line 8561 of CvUnitAI.cpp:

bool CvUnitAI::AI_spreadCorporation()
{
	PROFILE_FUNC();

	CorporationTypes eCorporation = NO_CORPORATION;	

	for (int iI = 0; iI < GC.getNumCorporationInfos(); ++iI)
	{
		if (m_pUnitInfo->getCorporationSpreads((CorporationTypes)iI) > 0)
		{
			eCorporation = ((CorporationTypes)iI);
			break;
		}
	}

	if (NO_CORPORATION == eCorporation)
	{
		return false;
	}
	bool bHasHQ = (GET_TEAM(getTeam()).hasHeadquarters((CorporationTypes)iI));

(last line)
i've changed iI to eCorporation (i think this change is correct), and then project has been built. I've get a CvGameCore_Release.dll and replaced an original one with this new file.
After i've launched the game, it crushed with memory access violation exception.

what do i do wrong?

i've installed visual studio 2003 so there are no problems now, all works ok.
