Error 403 and 202 when trying to look up for screenshots.

[RaptorZX4]

Almost all the time, i get Error 403 when trying to look for screenshots, and sometimes Error 202.

And when this happen, i can't close the screenshots window, OK and Cancel does nothing, only the Search button work. The OK and Cancel button work only if i selected a picture, and this could take between 5 tries up to 50 tries in the Search process, which is really annoying.
