Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
Sometimes it just takes a few days for a response.
Regarding the account disappearing you can simply re-register. They honored my warranty when I had to re-register.
Why not the L5639 everyone else have been buying up on eBay. I got one from my i7-950 as it was bottle necking my GPUs in BF4. They go for around $80 and you can use the same motherboard usually.
