Hey there. Hope you've all been doing alright.

So about a week ago I got my new computer with Windows 10 and decided that I might as well try to reinstall TEF today.

I did expect some problems, but nothing too hard to fix... The thing is that when and since I first ran the game, the dot stayed red and my connection status showed Error, with Connecting flashing through it very shortly every once in a while. You probably know what I mean.

Aside from running multiple instances of TEF all at once and messing around ingame hoping it'd connect, I have tried running as admin as well as compatibility mode (7, Vista, XP, 98), it wouldn't budge. Tried restarting my computer too.
I think I should also add that I'm running the game from D:, because C: is my SSD and it's not very spacious so I'd really prefer to not have to keep non-essential things there... Although I don't think that's the problem as I tried running from the default install location too and it acted exactly the same. This not-connecting is the only problem I've been having so far, no missing files or anything like that.
I'm beginning to think it could be due to my firewall/antivirus?

I was wondering if someone maybe knows what could be the problem or what else I could try?
I'm not very active anymore but it would be really nice to still be able to enjoy the forest sometimes... Maybe I'm not the only one who's had/is having this problem?

Thank you very much in advance. <3
