Picto problems, as in not spreading? Check your internet, even if it seems to be working.

It is an internet problem. TEF is very greedy with internet usage and is resource heavy. If yours is unlimited, check with your provider that you're getting what you pay for, they should happily run a speed check for your area. You can also do speed checks online. However, if your internet is shared (at college, right?) then this is more likely to be the main cause of your connection problems. when I have to share the internet with my brother when he's downloading on xbox live, I can forget about connecting to the forest.

Problems with connection are mostly to do with your internet. For example, my old laptop is very outdated, but it still connects to TEF instantly because I have good internet connection, despite the fact it will run at 1-3fps. I open it on my laptop if I have a problem with it on my pc, and if it can connect (which it does 90% of the time) it's because I'm doing too many internet-related things on my computer or my pc internet dongle is out of reach of the best wireless signal to the router downstairs. If both my pc and my laptop cannot connect, it is because my internet strength is too low to be adequate food for the game.

Hope that helps. If you're wireless, also try plugging your laptop/whatever directly into the router.

It's easy to tell if it's a computer hardware problem by how the game runs without being connected, by the way. If you can run around without blips and a high fps, it's completely fine.
