StreamWriter & xml reading problem

[Dumpen]

Hello.

I have this wierd problem when im writing to a text file with data from a array

I have this method:
private void writeData()
{
// Open file
StreamWriter writeData = new StreamWriter(saveMonsterSetBase.FileName, false);

// Write all data from array to file
for (int x = 0; x < MonsterSetBaseDataArray.Count; x++)
{
writeData.WriteLine(MonsterSetBaseDataArray[x]);
}

// Close stream
writeData.Close();
}

Which is trigged here:
saveMonsterSetBase.ShowDialog();

if (saveMonsterSetBase.FileName != "")
{
writeData();
}

It works fine and opens my saveFileDialog

But after I save it I get a "file not found" on some other method I use

This is some of the method:
// Opening txt file with location from XML
StreamReader findMonsterStream = new StreamReader(@XMLmonsterLocation);

I get the error monster.txt (XMLmonsterLocation) is not found

It looks like the writedata changes the local path because it says

File not found in the path where I saved the file

Example:
The application and monster.txt (XMLmonsterLocation) is saved in D:\

I then use the saveFileDialog (I save a file to for example C:\) and when I access my method where I use the XMLmonsterLocation it says file not found in C:\

So I dont know why

Hope you understand

The StreamReader reads from a xml file that looks like this:
<?xml version='1.0'?>
<config>
<monsterLocation>monster.txt</monsterLocation>
<monsterSetBaseLocation>MonsterSetBase.txt</monsterSetBaseLocation>
<monsterImageLocation>mobs\</monsterImageLocation>
<mapImageLocation>maps\</mapImageLocation>
<mapInfoLocation>maps\maps.txt</mapInfoLocation>
</config>
