Pdf form generated by asp does not open in IE8 after installing Reader X

Question

started using Reader X last week and when opening a pdf generated by asp it does not work but when I kill the process iexplorer.exe for that window I get:
"This tab has been recovered. A problem with this webpage caused IE to close and reopen the tab" and then my pdf opens. Thanks for any input or ideas.....

First of all, thank you for your interest and
Yes, my asp generates the pdf using fdf. Part of this is:
Response.ContentType = "application/vnd.fdf"
Set FdfAcx = Server.CreateObject("FdfApp.FdfApp")
' =======  Get/Create FDF and Set Values/Filename
Set oFDF = FdfAcx.FDFCreate
        oFDF.FDFSetValue "Loc", strLoc, false
        oFDF.FDFSetValue "Comp", strCompN, false
        oFDF.FDFSetValue "Symb", strSymb, false
        oFDF.FDFSetValue "PolNum", strPolNo, false
        oFDF.FDFSetValue "Mod", strMod, false
        oFDF.FDFSetValue "PolHol", strPolHol, false
        oFDF.FDFSetValue "Usr",struid, false
        rs.MoveFirst
        i = 1
        j = 1
        k = linp
        While (i <= npag)
            strData = ""
            while ((Not rs.EOF) and j <= k )
               strData =    strData & rs.Fields(22).value & VbCrLf
               'strData = strData & i & " - " & j & " - " & k & VbCrLf
                rs.MoveNext
               j = j + 1
            wend
            k = (j + linp) - 1
            if i <= npagaux then
                oFDF.FDFSetValue "WorData"&i,strData, false
            else               
                oFDF.FDFSetValue "WorData"&i,"Blank Page Left Intentionally", false               
            end if
            i = i + 1
        wend          
oFDF.FDFSetFile "http://" & request.servervariables("SERVER_NAME") &  "/pdf/myform.pdf"
Response.BinaryWrite oFDF.FDFSaveToBuf
oFDF.FDFClose
Set oFdf = Nothing
Set FdfAcX = Nothing

Thanks for your help.
