If you want a DEM converter try these:

They will allow you to convert DEMs into a format Vue can accept.

As Nano says, 90m is quite course, it might be suitable for distant mountains, but don't expect to pick out many details. You really need 10m or lower, but other than the US, it's not usually freely available.
