Hard to say.  Are you then getting a ton of "Bread" errors?  That would imply that the drive dropped offline.  And could be an issue with flash or the port.

Sometimes you can rectify such an issue by reformatting and recreating the flash drive.     Do you have a backup (as that will contain your key file and configuration files).    If that does not rectify the problem then it is possible the flash drive is failing.

No other errors apart from what was in first post.

 

Sorted just put backup on new stick and transferred license all good now.

I could have tried format on original but for the sake of few quid just got a new stick to be safe.

Cheers
