Powershell script works fine when fun from powershell console, but does not when run from batch file

I'm trying to run my powershell script from a batch file but I can't seem to get it to perform the same way when doing that.

If I run my powershell script from powershell console it works fine, if I run it form a batch file it doesn't work. The powershell script starts up a program called console, watches a folder for changes, and then backs up that folder when there are changes, it also listens for when the conlole program is closed and cleans itself up.

When running from a batch file, the batch file starts up the script using the powershell command, and the script does then still start the console application, and i see output for the register events, but then when a file is changed or added to the watched folder, nothing happens. Yet it does still print out the statement for when the console application closes. I'm not quite sure how to debug it :/

Sorry I don't know how to format the code on here, but I can send the file to someone if that's easier.
