The tool doesn't clear old temp files, and that's causing a name collision.
Workaround:
Each time you see the "error occurred... try again" dialog, open a Command Prompt window and type:
- del "%temp%\acq*.tmp.*" /a
Keep the CMD window on standby and rerun the command every time you see the error dialog. This will *significantly* reduce the number of times the error appears.
An even more effective method is to run a script that deletes older tmp.* files in that folder at every 5 sec interval.
