I was able to upload QSO's fine to LOTW from my QSO list last night but when I tried to download from LOTW I get this error:
Something is wrong because LoTW server returned invalid adif file header.
Your LoTW username/password could be wrong or LoTW server is down.
Do you want to show the file?
My username and password are correct and the LOTW site shows it is not down. I have tried several times today with the same result. Is anyone else having this issue?
