Audacity problem connecting to Lame


I unfortunately can not open mp3 encoding library in Audacity when I tried to export audio even though I’ve never had the problem previously. I have an older computer. I am not as of yet having MP3 Audacity problems with another computer that I have, but then I cannot get on the Internet with this one. At this point I am concerned about the Audacity/lame_enc.dll

I have downloaded the lame_enc.dll and once again have never had a problem before and I’ve been working with these files for years.
