Can't access 2nd worksheet

[SLIDE1]

Hola,
My issue is I can't access my 2nd workbook file when I use this code.
This works when app. is on E: drive

Sub DataLoad()
  'PURPOSE: This sub apppends Source Information Master File folder with approriate data
  'VARIABLE DIMENSION
  Dim strRANGE As String               'DATA RANGE
  Dim wbkActive As Workbook            'ActiveWorkbook
  Dim wsSourceData As Worksheet          'Data worksheet
  
  'VARIABLE SET
  Set wbkActive = Application.ActiveWorkbook
  Set wsSourceData = wbkActive.Worksheets("SourceData")
  strRNG1 = wbkActive.Names("RANGE1").RefersToRange
  
  
  'MAIN CODE
  wsSourceData.Range("A2:J2").Copy  'select the range A2 to J2, thats the data I need

  Application.Workbooks.Open ("E:\SOURCEDATAMASTER") ' Open the file to copy to

  Range("A65536").End(xlUp).Offset(1, 0).PasteSpecial _
        Paste:=xlPasteValues  'find the last row containing data, and then plus one, then paste the data

  ActiveWorkbook.Close SaveChanges:=True 'close and save the masterfile workbook


  'wbkActive.Activate 'bring the Source Input workbook back to the front

End Sub

When I substitute a different file path the code does not recognize the 2nd workbook.

Application.Workbooks.Open ("I:\SOURCE INSPECTION\SOURCEDATAMASTER")

Any and all help will be appreciated!
