Corrupted map files when using Allow Local Files

[Barade]

For my modification The Power of Fire I wrote a small program which enables the registry entry "Allow Local Files" and starts Frozen Throne afterwards.
My modification installs several directories into the Frozen Throne directory which should all be available during the game.
Unfortunately, when I start a map of the modification it says that the map file is corrupted.
When I start Frozen Throne without "Allow Local Files" I can start my maps without problems.
Therefore, I suspect that either any local file causes the problem in the Warcraft III directory or that it does not reall work on Windows 7.
The strange thing is that it worked before with MPQDraft and a custom exe before they patched Warcraft III. Hence, my own local files should actually work.
Is it because of the local Maps directory which does still exist in the Warcraft III directory?
Any ideas?
Is there any possibility to see some log files etc.?

edit:
I can still play some of the normal maps of Warcraft III like Warchasers an even some custom maps but not all with the Allow Local Files option.
I tried to delete most files in the Warcraft III directory which are not part of the installation but it did not help yet.

Nevermind. I had a "war3map.j" file in the Frozen Throne directory After deleting it I could play my maps.

Worth noting that there is a mpq dedicated for mods now. It might be more convenient to use that instead of relying on local files.

Which one?

Which one?

"War3Mod.mpq"

Didn't know that thx. Well, I mod starter would be useful which selects an MPQ archive and moves it to War3Mod.mpq and back to prevent collisions of multiple mods.
