FileOpen issue

[Marc Boggs]

      int handle = FileOpen(TickFile,FILE_READ|FILE_CSV,','); 
      if(handle < 1) 
      {  
         string strErr = Error(GetLastError());
         Print("Cannot open file " + TickFile + ": " + strErr); 
         return(false); 
      } 

I'm having a problem opening an ANSI csv file.  The file has full access permission for all users.  

I've tried putting it in:
"C:\Program Files (x86)\MetaTrader 4 at FOREX.com"
"C:\Program Files (x86)\MetaTrader 4 at FOREX.com\MQL4\Experts"
"C:\Program Files (x86)\MetaTrader 4 at FOREX.com\history"  (With FileOpenHistory)

Also specified the absolute file path.

The handle is always -1.  datafile attached. 

Any ideas?  

Thanks in advance.
