I have the light plugged into a x10 appliance Module. When I try to turn off the appliance module just clicks. I tried different modules.

Something doesn't add up in your description. More detail will help.
1) does the module click OFF and then right back ON? (or click rapidly three times and the light will flicker but remain ON).
2) Or when you hit OFF on a remote (you said you tried to turn OFF with "other X10 devices") does it click once but yet the light remains ON?
3) you said you tried other modules...do they "just click" also, or do they remain silent and do nothing?
4) try plugging a 4 or 7 watt incandescent night light (NOT LED) into the module along with the CFL, does it still refuse to turn OFF?
Alan is right about CFLs creating noise problems but your description of the module clicking may mean you have at least one module in the mix that may not like working with CFLs, especially if it goes "clickty, clickty, click" and works correctly with the night light.
