Hi Colescuttle, welcome to the forum !
Are you sure you're
holding down Func/set while pressing DOWN or DISPLAY ?
According to the camera's Wiki page
http://chdk.wikia.com/wiki/SX200IS it should work with 'ver.req'
on the card.
Also, verify you've got the name right: ver.re
q ends in a
Q not
Ghope that helps,
wim
edit: since the 2 firmware versions known for SX200IS (100c & 100d) are identical from the viewpoint of CHDK
you could also just try either one ...
