Yeah I have checked the date and time first thing I did, how do I copy the chain from my other computer ?

Hi, this may sound stupid what im asking but im not the best with computers so please forgive me and im learning, if I click the back up wallet button in file can I save this straight to a USB or anywhere on my computer or is there something more I should be doing, I tried reading about the backing up somewhere thru disk management but I cant figure it all out, can someone please explain. Is there a plain an simple way for somebody like me.

thanks

Hi, can anyone help please have downloaded the new bitcoin QT to my new computer it downloaded all blocks and has finished but the green tick wont appear and it keeps telling me that its catching up now a whole day catching up isnt right, I have downloaded the same one to my other older  computer a couple of days ago same version 0.8.1 no problem can send and receive coins green tick shows up within a min once turned on, now I have deleted the client from the new computer and redownloaded it serveral times but samething once it reopens up little circle just keeps going around downloads blocks an stays up with all the correct amount of blocks but that's it no green tick still says catching up.....? Any body please very frustrating...

PS. when I reopen it, it tells me, ( Warning: please check your computers date and time are correct! If your clock is wrong Bitcoin will not work properly.

Thanks
