Problems with Warcraft III-WorldEditor

[Stigoz]

Every time i try to launch Ryoko TD version 2.5 Full, and other downloaded, advanced maps worldeditor crashes...

What's happening?

The maps are protected. You won't be able to open them.
And we don't support opening protected maps.

This is most likely or:
1. The map is protected, as said.
2. The map was made in WEU or any other WE with triggers/whatever that aren't supported by the original one.
3. Same as above, but even maps from TFT updated will crash if you run them on a not-updated TFT WE, this also counts for RoC ofc, and tft maps can't be opened using a RoC Editor too.

That should be all.. it's a nonsense error AFAIK
