Error finding a file

Question

I've downloaded and installed the Stanford Parser to use with a project of mine and I am having problems with running the Demo of it.
I'm getting an error which is listed below:
Loading parser from serialized file englishPCFG.ser.gz ...
Exception in thread "main" java.lang.RuntimeException: File not found: englishPCFG.ser.gz

I have checked to see if the englishPCFG.ser.gz file is there and it is. I also checked to see where the file is being called from. the default location which has been provided with the program is
"/u/nlp/data/lexparser/englishPCFG.ser.gz"
the actual file is located in
C:\Documents and Settings\Mitesh\Desktop\eclipse\stanford-parser-2010-02-26\stanford-parser-2010-02-26\englishPCFG.ser.gz
I tried to input this location into the code but it still comes up with the same error.m

Sorry, I've just been trying to get it to work all weekend and haven't had any luck.
import java.util.*;
import edu.stanford.nlp.trees.*;
import edu.stanford.nlp.parser.lexparser.LexicalizedParser;
class ParserDemo {
  @SuppressWarnings("unchecked")
public static void main(String[] args) {
    LexicalizedParser lp = new LexicalizedParser("englishPCFG.ser.gz");
    lp.setOptionFlags(new String[]{"-maxLength", "80", "-retainTmpSubcategories"});
    String[] sent = { "This", "is", "an", "easy", "sentence", "." };
    Tree parse = (Tree) lp.apply(Arrays.asList(sent));
    parse.pennPrint();
    System.out.println();
TreebankLanguagePack tlp = new PennTreebankLanguagePack();
GrammaticalStructureFactory gsf = tlp.grammaticalStructureFactory();
  GrammaticalStructure gs = gsf.newGrammaticalStructure(parse);
  Collection tdl = gs.typedDependenciesCollapsed();
  System.out.println(tdl);
  System.out.println();
    TreePrint tp = new TreePrint("penn,typedDependenciesCollapsed");
    tp.printTree(parse);
}this is a snippit of the LexicalizedParser Class where the source is defined.
public Options getOp() {
    return op;
  private Options op;
  private static final String SERIALIZED_PARSER_PROPERTY = "edu.stanford.nlp.SerializedLexicalizedParser";
  //private static final String DEFAULT_PARSER_LOC = "/u/nlp/data/lexparser/englishPCFG.ser.gz";
  private static final String DEFAULT_PARSER_LOC = "C:/Documents and Settings/Mitesh/Desktop/eclipse/stanford-parser-2010-02-26/bin/englishPCFG.ser.gz";i commented the original line out and added my location here.
