Does not equal com.mintry.ruinsoftime.proxy.ClientProxy

Change your string to the latter. And you'll also want to change your CommonProxy one.

On that note you should change your proxy system a bit. Get rid of CommonProxy and repalce it with ServerProxy and make both of your proxies extend from an interface you will create typically called IProxy.

The reason for this is a CommonProxy is your "Main" class(@Mod class).

They have to implement IProxy yes, Then you change the @SidedProxy field in your Main class to IProxy.

We don't teach Java here. If you don't know what implement means search it on google. If you don't know what a field is look that up on google. Otherwise you'll need to be more clear on what you are having a problem with.
