Persits.upload problem

[.Net Sports]

I'm using Persits.upload module in ASP, and when i use the following
form pointed to the object I've always used, i get a "The system
cannot find the file specified" error pointing to the line of my
upload.savevirtual :

Set Upload = Server.CreateObject("Persits.Upload")
upload.savevirtual ("test/")

..
''''error:
Persits.Upload.1 error '800a0005'

The system cannot find the file specified.

/upl/aspupload1.asp, line 5


'''form
<form action="aspupload1.asp" method="post" enctype="multipart/form-
data">

<input type="file" size="40" name="FILE1" />

<br />
<input type="submit" value="Upload!" />
</form>


<form action="aspupload1.asp" method="post" enctype="multipart/form-
data">

<input type="file" size="40" name="FILE1" />

<br />
<input type="submit" value="Upload!" />
</form>
