yeah i know what brantje was saying but like i said i have no idea on doing / creating a VM
an i'm not on 5644 as when i came out there was issues with it to start with an mine was working fine so went on the if it's not broke don't fix it theory, but obviously updates / bootloaders came out and solved the issues but i didn't upgrade as i was busy doing other things but im free again to do the upgrade now
you reckon going straight to DSM 5.2 5644 update 5 will be fine ??
