Excel宏在某段时间后无效

Question

我在Excel中有一个从特定链接获取数据（html表）的宏，该宏可以正常运行4-5次，但之后会得到空白数据。但是如果我再次记录那个宏并且运行它再次正常工作4-5次运行。我该如何解决这个问题？

添加下面的宏（这是录制的宏）

使用ActiveSheet.QueryTables.Add（连接：= _         ＆＃34; URL; HTTP＆＃34; _         ，目的地：=范围（＆＃34; $ A $ 3＆＃34;））         .Name = _         ＆＃34; awadmin命令名= appwatch＆安培;？项目= 60115蛇毒＆安培; I = 1和M = ＆安培; Q = ＆安培; GO =提交＆＃34;         .FieldNames = True         .RowNumbers = False         .FillAdjacentFormulas = False         .PreserveFormatting = True         .RefreshOnFileOpen = False         .BackgroundQuery = True         .RefreshStyle = xlInsertDeleteCells         .SavePassword = False         .SaveData = True         .AdjustColumnWidth = True         .RefreshPeriod = 0         .WebSelectionType = xlEntirePage         .WebFormatting = xlWebFormattingNone         .WebPreFormattedTextToColumns = True         .WebConsecutiveDelimitersAsOne = True         .WebSingleBlockTextImport = False         .WebDisableDateRecognition = False         .WebDisableRedirections = False         .Refresh BackgroundQuery：= False     结束//从URL获取数据

Cells.Replace What:="Display System Objects", Replacement:="", LookAt:= _
    xlPart, SearchOrder:=xlByRows, MatchCase:=False, SearchFormat:=False, _
    ReplaceFormat:=False
Range("C8").Select
