Thank you for your message. the error you are receiving suggests that another Process or Application is also using that status file currently. Do you have any other installations of Xibo on your PC? I would recommend making sure that you do not have more than one Player installed on the PC, just in case this is causing a conflict.
You may find that using a tool such as Microsoft Process Explorer will reveal what other Processes are accessing the file, which will help to understand the issue. I hope you are able to narrow down what on your PC is accessing that file, perhaps an antivirus may be accessing the file at that time, which could also cause a conflict like this.
