Image I/O memory error

[whiteblood]

Hi guys,

 

I've just got back into 3d max and decided to start using vray and HDRI. I put my backplate in, set my cameras etc, Then I try to put the actual hdri into the environment slot. When I try to do this it comes up with "image I/O error" it states the file location then underneath then "memory error". I know the hdri files are pretty big but my computer isnt too bad.( Im running intel i7 quadcore and 4gb ram). Any suggestions as why this is happening and is there a way around this problem. Thanks in advance
