      I purchased a stand alone copy of CS4 in 2009/10 from a well known company.  I upgraded the memory on my MAC a few weeks ago and now I can not open photoshop.  It says error 6, your licensing has expired.  I have several presets and overlays in this version that I have created or purchased.  I still have the original serial number along with the original CD.  How can I correct this?
