It may depend on whether you have the "Home and Student" version that, according to this website, http://coreldraw.com/blogs/gerard/archive/2010/09/22/introducing-coreldraw-home-amp-student-suite-x5.aspx does NOT support VBA (macros).
There is also an "Education" program at Corel that offers the full package at reduced rates to educators. It has the "Not for commercial use" designation, as does "Home and Student".
If you already have the software, it is easy to check by going to the Tools menu to see if macros are listed.
I hope this information is helpful.
