Try going to adobe.com
-Download the trial and install it
- Use the trial for a little bit
- Before the trial ends, or is near ending download a crack for it off TPB- They come with all instructions in the download of the crack, and should be really simple. Just do not activate your product, register it, or update it. And make sure the crack is compatible with the version of Photoshop you download from Adobe.com (Adobe Photoshop CS5 Extended)
Dont download the master suite, just photoshop.
