I see nothing wrong with your code. I know this may sound strange, but on occasion, I have had to slow processes down so that a single "complex" or "time" consuming process can completely finish before executing the next step. I have had to add a Timer function following some commands to get them to process correctly. It usually takes only one second to clear the way, but it works.
Try inserting a Timer following the Tool bar deletion prior to FileClose. Since I can’t see anything wrong with your code, I have no idea of anthing else to try.
Here’s a trimmed down example from the VB Help screen.
Dim PauseTime, Start
PauseTime = 1 ' Set duration.
Start = Timer ' Set start time.
Do While Timer < Start + PauseTime
DoEvents ' Yield to other processes.
