I am using a vacuum press. The water is getting sucked up into the top chamber no problem but the coffee is only partially draining back down. Can anyone help?

The plastic filters on these work very well, provided the ground coffee doesn't have too much in the way of fines (dust) in it. If it does, it just clogs the grooves in the filter stopping the brew descending.

First thing you need to do is buy a good multi use burr grinder. A referb from Barazta is fine, but it is hit or miss as to what is there. A Click Here (www.baratza.com) encore is a good little grinder if you want to have a motorized one. For hand grinders, you could use a Hario Skerton such as this one Click Here (www.sweetmarias.com)
Your coffee goes stale very quickly, like in 15 minutes from being ground. then again, if you are buying from a supermarket, it is extremely likely that it is was stale months ago. Roasted coffee is only good for about 15 days in espresso use and a little longer, say 3 or so weeks for other brewing methods.
Fresh coffee, freshly ground will be a huge improvement in what you drink, even if you DO get the water to go back down.
As others have said, too many fines can clog the system. Your bed of coffee acts as a filter on the water returning to the bottom, if you clog your filter, you stop the flow of water.
The other thing to check for is that you have a good seal between the two globes. The water is pushed UP from the bottom one by the pressure of the water heating up (hot water expands) and the water returning down is sucked down by the lower pressure in the lower globe. If there is a vacuum leak, you will not get all the water to return down to the bottom globe.
