VB6

I would like to create a tool for receiving emails and attachments.
Then
1.I download BASP21-2003-0211.exe from http://www.hi-ho.ne.jp/babaq/basp21.html[^] with the link Down Load! BASP21-2003-0211.exe (1.44MB) and installed the exe.
2. I register c:\windows\system32\basp21.dll with the command regsvr32 basp32.dll
3. I added the reference "Basp21 1.0 Type Library" and coded

Dim oboj As New BASP21Lib.Basp21
Dim obj As Variant

obj = oboj.RcvMail("pop.gmail.com" & vbTab & "995", _
                    "fortestman@gmail.com", _
                    "fortestman", "STAT", "D:\Workplace\")

MsgBox obj

4. It always shows the error: POP3 error. What should I do? Please make use of this email address for example to tell me how to solve this problem. Thanks ahead.
