Flash AS3 & Base64 Library = comile errors

Flash AS3 & Base64 Library = comile errors

I have a problem using Sociodox BASE64 LIBRARY library
(sociodox.com/base64.html). I'm totally newbie in Flash so please help.
I've connected the library with "import com.sociodox.utils.Base64;"
After that I try to compile my project but get the following error:
Base64.as, Line 146: 1100: Syntax error: XML does not have matching begin
and end tags. Base64.as, Line 146: 1084: Syntax error: expecting
rightbrace before end of program.
Here is a screenshot of the errors: clip2net.com/s/5Jbzlt
Please advise!
