Srand (Time(NULL)); is being weird

    }

}

int main()
{
    srand(time(NULL));
    int LevelDifficulty = 1;
    const int MaxLevel = 5; 

    while (LevelDifficulty <= MaxLevel)//Loop game until all levels are completed
    {
        bool bLevelComplete = PlayGame(LevelDifficulty);
        std::cin.clear(); //Clear any errors
        std::cin.ignore(); //Discard the buffer

        if (bLevelComplete)// will increment levelDifficulty by 1 
        {
            ++LevelDifficulty;
        }   
    }

    std::cout << "\nCongraulations You have collected all 5 Excaliburs!\n";

    return 0;
}

Has anyone else had this problem?
When ever I have srand (time(NULL)); in my int main, block of code, and compile it.
And i start to play the game at level 3 after 5 second passes, it ends the game there and exits the code.
To play the game again I have to compile the game again.
If i take srand(time(NULL)); out I have no problems.

Do you have an antivirus? If so did you compile with /Zi?

cl triplex.cpp /Zi

Thats fixed it. Thanks
