I an referening the file from class Engine into class DataAccess

Could someone have a look for me please
Many thanks

package StatPairsModel;

import java.io.IOException;
import java.util.Hashtable;

public class Engine {
public static void main(String[] arguments) {

Instrument stock1 = new Instrument();
Instrument stock2 = new Instrument();

//PROBLEM WITH NEXT LINE - IOException
DataAccess tsData = new DataAccess
("c:\PairsData\timeseries.txt");

stock1.setStock("0015425", "Vodafone", "VOD LN", "UK", "TELECOM",
"GBP", "VOD LN", "FTSE");
stock2.setStock("0045125", "Telecom Italia", "TIM IM", "IT", "TELECOM",
"EUR", "TIM IM", "MIB");

If you are using windows you need to use forward slashes in the file path.
