Config file not saving

Hi, I am trying to write to a config file in MC 1.8.9. I type in the new value (90, previously 45), press done, and I go back in the config, and it's 45 again! Code to write to value:

public static void syncConfig() {
	    try {
	        config.load();
	        
	        Property configFOV = config.get(Configuration.CATEGORY_GENERAL,
	                "FOV",
	                "45",
	                "Amount to zoom to");

	        FOVVal = configFOV.getInt();
	        System.out.println(FOVVal);
	    } catch (Exception error) {
	        
	    } finally {
	        config.save();
	    }
	}

Code for detecting if done button is pushed:

protected void actionPerformed(GuiButton button)
    {
        if (button.id == 2000)
        {
        	FOVMod.syncConfig();
            boolean flag = true;
            try
            {
                if ((configID != null || parentScreen == null || !(parentScreen instanceof FOVGuiConfig)) 
                        && (entryList.hasChangedEntry(true)))
                {
                    boolean requiresMcRestart = entryList.saveConfigElements();

                    if (Loader.isModLoaded(Reference.MODID))
                    {
                        ConfigChangedEvent event = new OnConfigChangedEvent(Reference.MODID, "FOV", isWorldRunning, false);
                        MinecraftForge.EVENT_BUS.post(event);
                        if (!event.getResult().equals(Result.DENY))
                            MinecraftForge.EVENT_BUS.post(new PostConfigChangedEvent(Reference.MODID, "FOV", isWorldRunning, false));
                        
                        if (requiresMcRestart)
                        {
                            flag = false;
                            mc.displayGuiScreen(new GuiMessageDialog(parentScreen, "fml.configgui.gameRestartTitle", 
                                    new ChatComponentText(I18n.format("fml.configgui.gameRestartRequired")), "fml.configgui.confirmRestartMessage"));
                        }
                        
                        if (parentScreen instanceof FOVGuiConfig)
                            ((FOVGuiConfig) parentScreen).needsRefresh = true;
                    }
                }
            }
            catch (Throwable e)
            {
                e.printStackTrace();
            }
            
            if (flag)
                mc.displayGuiScreen(parentScreen);
        }
    }

I have been working on this for hours, and any help would be appreciated greatly. Thanks!
