My other message was incomplete, it was a mistake: This is the correct one

When I run the script I got the next error:
>>> import crawler_shp
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "crawler_shp.py", line 105, in <module>
    dbf = Dbf(d,new=False)
  File "C:\Python26\lib\site-packages\dbf.py", line 125, in __init__
    self.stream = file(f, ("r+b", "rb")[bool(readOnly)])
IOError: [Errno 13] Permission denied: 'R:\\Aplicaciones\\IRISv3\\mis
proyectos\
\HURACAN\\BUFFER1000.dbf'

The error is pointing to a library I used to make the script run: dbf.py. in
thid lines:
if isinstance(f, basestring):
            # a filename
            self.name = f
            if new:
                # new table (table file must be
                # created or opened and truncated)
                self.stream = file(f, "w+b")
            else:
                # tabe file must exist
                self.stream = file(f, ("r+b", "rb")[bool(readOnly)])
