Links Sports.NET

I am almost 80 years of age and have difficulty with technical tasks and dementia. I have played LINKs for 30-40 years in it's various upgrade forms. About a year and a half ago, my home computer was hacked by Russians (Ukraine so they claimed) and replaced by me; some files from the original CPU were transferred to the new computer(not by me). I was given another LINKS user name and password. The program would let me play in both online and offline modes but would not accept my old user name and password and data for online play. I have been playing offline the past 1 and 1/2 years. I love and miss Links online golf very much. How can I retrieve my original user name and data so I can play online? I NEVER THOUGHT ABOUT ASKING YOU GUYS BEFORE. I HAVE POSTED FOR HELP IN PAST YEARS. JUST FORGOT I GUESS!
