Lost my wallet suddenly?

Hi,

I just removed older version of my nem and tried to open to open my wallet. The name of my old wallet does not shows up on the client so i cannot log in. I do not remember my NEM address so did I just lose everything?

What i could do?

how did you remove the older version?

Just removed the folder… But i find my address and i have the private key so then I suppose there should not be any problems to gain access to my wallet/account?

If you still have the private key you are safe.

Which folder did you remove?
