Are you CPU mining or GPU mining? If GPU mining my suggestion to you would be not to use software that has not been updated since January 2016, and use the appropriate mining software for your GPU.
If you are CPU mining, you’re using spending more on electricity than you are making.
Your zcash address is invalid, there is probably some copy&paste mistake somewhere.
You can check validity of address with zcash-cli like this:
$ zcash-cli getaccount t1LXR5irMhAEtq8x1wqZsahLuNF4UDeK2ds
error code: -5
error message:
Invalid Zcash address
I’m glad you got the invalid Zcash address resolved; I just want to mention that if you are using Nheqminer to GPU mine you need to use a different mining program.
