[SOLVED] How to compress large DSL files (more than 1.8 GB)

I downloaded the 2012 version of Urban Dictionary in dsl format, its size is 2,4 GB. It works well in GoldenDict.
I tried to dzip it in Ubuntu from command line and, although the conversion seems to complete succesfully, the resulting 418MB .dz file doesn't work in GoldenDict.
Then I tried to convert it in Windows with dictzip.exe, but the compression doesn't start at all: the programme is closed with an error message and a 0 bytes .dz file is created.
Could you please help me or try to do this for me? The dictionary can be downloaded here: http://goo.gl/4eHFuH (don't worry, it's a 7zip compressed file of only 199MB
