Can't relaunch Warcraft 3

Error handling request pops up when i reinstall the game. I used the Classic Key to play Wc3 on BN before i went on a hiatus which worked.

For context I haven’t touched the game in quite a while and only recently reinstalled in via However, when i launch it it had an error handling request. I went to redeemed both my Classic ROC and TFT keys and say they are already taken, by me I believe, since there was a Warcraft 3 Reforged Account in my Account Details.

To reiterate, I have been able to run this before without any errors. This error only started when I reinstalled it and tried to play it.
