Thank you the prompt reply.
I totally understand, I also think its an isolated issue.
I did try to reinstall LB a few times. Uninstalling, rebooting and installing again on H: drive.
The installation file size is: 218 MB (228,721,746 bytes) (On disk its 218 MB (228,724,736 bytes))
I will try to uninstall again and this time install LB on a different volume..
I am using McAfee but I disabled file protection and the firewall, so maybe this is not the reason.
Will let you know if it works
