\beta is part of the core latex distribution.

if you had bothered to report what the error was, i could be more
helpful than merely using my crystal ball:

"missing $inserted" is corrected by putting the \beta in maths, so you can change: ... this is a \beta-version ... into either ... this is a \ensuremath{\beta}-version ... or ... this is a$\beta\$-version ...

the first form is preferred, since it's more robust, but the latter
is less typing.
