I already have war thunder on my pc

I already have war thunder on my pc,should I uninstall it and then reinstall it?

You can do some tasks only if you never played the game before. I'm not sure about this one, and how it is being tracked. I sure do recommend you reinstalling the game, but your IP might already be noted as "known".

Damn,wish i knew about gamehag before I started playing wae thunder.

But you always can try it. It is worth the risk looking at the reward. Otherwise I recommend you GW2, good rewards!
