Network error since Firmware Update

Hello, I hope that someone cvan help. Since applying the latest firmware update I have not been able to get into my folders through my laptop. My PS3 can see the folders and my laptop can play anything on the folders through media player. 

I have tried remapping the drive and folders but it will not let me - keeps coming up with ‘Network error’. 

I am currently using Windows 8. Nothing else has changed and I have even disabled AVG just in case it was a firewall isssue. Look forward to hearing any suggesitons and please let me know if you need any further information.

Best,

Mike
