This is probably due to an issue with either your browser or Flash Player version.
We would advise that if this is a problem that you have been experiencing you should first try and download the latest version of Adobe Flash Player and use Google Chrome as an additional browser.
We have tried these changes at the club and they have worked.
If the problem still persists after these changes we would recommend you contact Perform Customer Services on the following e mail: customerservices@performgroup.com
