Error 8:Syntax error.
Line:38
-> #target photoshop
I've been getting this too (Windows XP, Photoshop CS2) but have just managed to sort it out.
Go to the location of Chartthrob C:\Program Files\Adobe\Adobe Photoshop CS2\Presets\Scripts\ChartThrob.jsx
Right click on ChartThrob.jsx, then left click on Edit. This brings up a page of text and on line 38 you will see #targetphotoshop
Erase that text, so that line 38 is empty. Save, then close. ChartThrob should now open properly from the Scrips menu in Photoshop.
Well, it worked for me...!
