Recently upgraded my operating system and put Adobe Creative Suite 2 on my
computer and was told that I would be able to still access my Freehand
documents all the way up tp FHMX but now I'm realizing that this was false
information. The Adobe tech told me that there could be plugins that would
allow my to open these files and would like to get more information regarding
this issue from this forum.

There are no plugins that I know of for CS2 that help you open FHMX files. Only
Illustrator CS3 opens native FHMX, 10 and 9 files. FH 8 and below you have to
Import. What operating system are you using? You can still use FHMX.

What level of CS3 would I have to upgrade in order to read these FHMX and FH10
docs? Would it be premium or standard? Also, after the upgrade to OS 10.4.6
Tiger we are unable to make FHMX run because the serial number window is locked
and will not let me click "ok" after I type in the serial number. I think this
was a student version of FHMX. Would that have anything to do with it?
