Synching one tree with AMT and two computers

Can I link and synch a tree to a PC and laptop? Using FTM 2012 and Windows 7. Learning how to use the synch function on my PC where the file is currently linked and synched with AMT. I want to link and synch the tree with my laptop as well. I was using DropBox cloud feature to synch my two computers, but the synch funtion often doesn't work (hangs up in the middle of the process) and I think the problem may be that "synch functions are trying to update at the same time resulting in a conflict.
Thanks
