change preview image issues

[EricTsuei]

I am using tactic4.5 and chrome.
and try to make my custom VFX template project. not by using VFX template.zip file.

So I create a clean windows server and reinstall everything. both pgsql and apache version are the same.
and tactic works.

so I try to move the asset and temp folder, from "c:\programdata\"  to "D:\tactic_asset\"
I change this setting in tactic page:  admin/link/system_config, then save.


But I can't check-in or change preview images anymore.
       

So I change the all the path back to c:\programdata\

Still can't check-in or change preview images. 

But I can check-in or change preview images in another tactic server which I already in use for 3 projects.

So I copy the file " C:/ProgramData/Southpaw/Tactic/config/tactic-conf.xml " from my old tactic server to the new one.

But still Can't.

seems tactic already make the ticket folder in " C:\ProgramData\Southpaw\tactic_temp\upload\ " but there's no images in them. seems upload fail.

here is the part of the log file I found in "C:\ProgramData\Southpaw\tactic_temp\log" please see the attachment.

one more, I am not testing check-in or change preview image before I change path setting in this new server. I tested in the old server and works.
