all of a sudden my file importer stopped working on me and started giving an access violation. i didn''t change a thing. here is my import function (i know its messy):

void Import_Obj()
{
	fseek(infile, 0L, SEEK_SET);

	outfile << "Import_Obj()" << endl;

	while(!feof(infile))
	{
		fscanf(infile, "%s", &stream);
		S_stream = stream;
		outfile << stream << endl;

		if(S_stream == "*GEOMOBJECT")
		{
			num_obj++;
			Mesh_array.reserve(256);

			Mesh_array.resize(num_obj);

			//outfile << "*GEOMOBJECT" << endl;

		}
		
		if(S_stream == "*MESH_NUMTVERTEX")
		{
			fscanf(infile, "%i", &Mesh_array[num_obj-1].num_t_vertex);

			//outfile << "NUM tVERTEX" << endl;

		}
				
		if(S_stream == "*MESH_NUMVERTEX")
		{
			fscanf(infile, "%i", &Mesh_array[num_obj-1].num_vertex);

			Mesh_array[num_obj-1].vertex.resize(Mesh_array[num_obj-1].num_vertex);
			Mesh_array[num_obj-1].vnormal.resize(Mesh_array[num_obj-1].num_vertex);

			//outfile << "NUM mVERTEX" << endl;

		}

		if(S_stream == "*MESH_NUMFACES")
		{
			fscanf(infile, "%i", &Mesh_array[num_obj-1].num_faces);

			Mesh_array[num_obj-1].face.resize(Mesh_array[num_obj-1].num_faces);
			Mesh_array[num_obj-1].fnormal.resize(Mesh_array[num_obj-1].num_faces);

			//outfile << "NUM FACES" << endl;

		}

		if(S_stream == "*MESH_VERTEX_LIST")
		{
			fscanf(infile, "%s", &stream);									//inputs bracket

			//outfile << "VERTEX LIST:" << endl;


			for(int i=0; i<Mesh_array[num_obj-1].num_vertex; i++)
			{
				fscanf(infile, "%s", &stream);								//inputs "*MESH_VERTEX"

				fscanf(infile, "%s", &stream);								//inputs vertex index


				//Y and Z values are swapped for 3D Studio files

				fscanf(infile, "%f", &Mesh_array[num_obj-1].vertex[i].x);	//converts x value & stores it

				fscanf(infile, "%f", &Mesh_array[num_obj-1].vertex[i].z);	//converts z value & stores it

				fscanf(infile, "%f", &Mesh_array[num_obj-1].vertex[i].y);	//converts y value & stores it

this is not the &#111;nly ASE file it does this &#111;n.  the parser always stops at the same spot.  any ideas what could be going wrong?
thanks ahead of time

ive just wrote one today!
i can send it to you if you want. it loads vertex, normal, texture coord arrays and indicies (the texcoord loads incorrectly i think)
