Problems with ListObjects function using VB

I have a VB 6 program that is using the ListObjects function to pull out all of the Documents in a Livelink Folder. I works fine when I run it once but when I run it again (without restarting the VB), it hangs on the ListObjects call. It does not return an error it just hangs and after about 10 seconds it kills my VB program. Any ideas on what I might be doing wrong? Here is a chunk of my code. I am just testing this out so it just pulls out all the doc names and puts them in a text box.status = LL_ValueAlloc(resultset)If (status <> LL_OK) Then MsgBox "Could not declare resultset"End If status = LL_Initialize(LL_HEADER_VERSION)status = LL_SessionAlloc(session, "localhost", 2901, "Livelink1", "admin", "lladmin") If (status = LL_OK) Then status = LL_ListObjects(session, -2000, 6504, vbNullString, vbNullString, LL_PERM_SEECONTENTS, resultset) If (status = LL_OK) Then status = LL_ValueGetLength(resultset, length) ' get length of the recarray textList = "" For i = 0 To length - 1 docName = "" docComment = "" status = LL_TableGetString(resultset, i, "Name", docName, 255, outSize1) status = LL_TableGetString(resultset, i, "Comment", docComment, 255, outSize2) textList = textList & "- " & Left(docName, outSize1) & " ---- " & Left(docComment, outSize2) & vbCrLf Next Text1.Text = textList Else Text1.Text = "Was not able to Retreive any Documents." End IfElse Text1.Text = "No Session Established"End If LL_ValueFree (resultset)LL_SessionFree (session)LL_Uninitialize

1. LL_ValueAlloc should not be called before LL_Initialize. This is stated in the documentation under LL_Initialize. "This function must be executed before any other Livelink API function is called."2. If you truly are invoking this code multiple times within a process, please note that you should only call LL_Initialize and LL_Uninitialize once per process. It is quite possible that the second LL_Uninitialize is causing problems. This is stated in the documentation under LL_Unintialize. "This function must be executed after all Livelink API processing is complete."
