EP6 PDK import

I have imported PDK 6.2.1 from iviewstudio - no problme there. I have downloaded 6.2.2 from here, but when unzipped the files are in 3 directories and are EPT etc. The Transport/import only seems to take EPA etc and the SDM seems to prefer swc files.

Can someone tell me how to bring in the 6.2.2 files and should I try and remove 6.2.1 first?

Also any notes on adding the Eclipse plugin in would be helpful

thanks.
