Forgot the combo

if you have forgotten the code, then the only way to get the lock open would be to 'progress' the combo. to do this - you will start say at 0000 and try the lock, then 0001 try the lock then 0002,0003,0004,0005 etc .. all the way thru all the numbers until you do hit the right combo and the lock opens. this will take anywhere from 1 1/2 hours to 2 hours to go thru all the way to 9999,, but since the correct combo will be somewhere in between, it should only take about 45 minutes to a hour to get the lock open. now what will help in the speed of finding the combo is if you can remember one or two of the numbers ( example: 5400,5401,5402,5403,5404,5405,5406 etc... ).
I am not sure what city you live in - but there is a chance that your local locksmith shop may have what we call ' readers ' -- and with these 'readers' there is a way to figure out the combo in about 3 minutes and a cost of about 15 dollars,, so you can call around to some of the shops in your area and see if they have them and are able to open the lock for you.

I forgot the master combo and now i cant get it...can i reset it?

I don't know if Master Lock will supply a combination or not but they can open it for you. There might be ownership issues that need verified. They don't know who's keys are in it and they don't know if the lock has been stolen.

I have a v60 master lock for a locker, how can i find the combo to open it again?

Take the lock if at all possible to a locksmith. You might be able to find one on fixya's directory. All locks have a code on the back. Manufacturers will not give the key codes or combos out so you will need a locksmith. The locksmith will contact the manufacturer or look up in his book your combo. For security reasons they are recalcitrant about giving you the combo unless you walk in with it. Otherwise you may have to call them out. The service call stinks but how do they (the locksmith) know that you are the actual owner of the lock? So they will need to verify all that. I hope this locks your problem in.
