Access to Excel Export - Unresponsive

I'm in the process of creating a code to copy and paste values within access
and then export the data to an excel worksheet. When I run the program, the
data that I want copied and pasted does so just fine. However, when the
module is done, access becomes unresponsive, forcing me to restart the entire
program. Can anyone tell me what's going on.
Also, I can't seem to figure out how to get access to open the excel
workbook to the correct worksheet and then paste in the new row of data at
the end of the existing data.
Below is the code I've written thus far. Any help you could provide would
be greatly appreciated.
