Lightroom problem

[bs0604]

I have a problem with LR. When photos uploaded a third are fine, a third have colored bands and a third have an exclamation point within a triangle and when opened state "An unexpected end of file occured". No problem when uploaded to iphoto. I got a new SD card but did not resolve this issue.
Nikon D90 LR 2 version 2.3 MacBook Pro 10.6.8
Any thoughts? Need a new updated version of LR?
