I...a have used the file .def in Virtuoso.
Try see if the version of the Soc-Encounter and Virtuoso are the same.

Define "huge". I've streamed GDS2's in the tens of GB no problem, but of course I was in 64 bit mode on a machine with 72GB or more of RAM. How much memory in your computer? 64bit mode?

If you have limited memory you might try only merging the cells you need to see. I.e., leave out IO cells, macros, or things you don't need to work with in Virtuoso.

If you have oasis support convert the GDS to Oasis which produces a file about 10x smaller. If you need a convertor, just use the freeware KLAYOUT. It can handle massive files.
