As we all know, Easy Paint Tool SAI is a great software...
But there's a problem...
it's trial only :<
Now I'll tell you how to reset the trial *grins*
Note Probably won't work if you already uninstalled it before
1) Open folder option
2) Uncheck "hide protected operating system"
3) Go to C:\Documents and Settings\All Users\Application Data\SYSTEMAX Software Development\SAI and you'll see these
4) Delete all *.ssd files which means delete everything you see, because that "thumbnail" folder contains *.ssd files
Run your SAI and you'll see...
Is it a good sign? Of course choose "OK"
HOHOHO TEH RESULT:
...and don't forget to check "hide protected operating system" back, because you'll see unnecessary files
However, do not open *.SAI file which is older than 30 days. If you already did, you'll have to reset SAI again.
