It is worth uninstalling and reinstalling after each update. It's a little more time consuming, but it makes certain that you aren't getting any corruption from the overwriting/update.
Additionally, when people are asking for more details/info, they're asking which Xbox you're using. Are you using the hard drive in the Xbox or an external one? Sad or HDD if external? On wifi or hardwire? Etc.
They have brains and are trying to help you troubleshoot but you're just whining instead of helping them help you.
Also, if it took you that long to download the new patch, you should get with your internet provider. For a game like this, you need faster internet because there is so much data being exchanged. Run a speed test at speedtest.com to see what you're actually getting versus what you are supposed to be per your ISP.
If all that fails, play a different game for a week or two until the next update comes out.
