CTD Issue

[skylane]

Hello!
I have a problem, maybe someone can help me..
I just discovered that my FS2004 crashes to desktop when I try to change the weather via the User-Defined weather settings. The pre-installed weather models work fine.
I have a CalClassic install, the last thing I did to it was adding the Silver Wings package. So I thought, maybe I messed something up with it, went back to the original, but the CTD problem didn´t go away.
Now I deleted the Classic install (I have a backup on an external harddrive, before the addition of Silver Wings) and reinstalled the original sim from the CD.
And I have the same CTD issue with the fresh install!

Has anyone seen this before, or any ideas what could be wrong?

Thanks,
Wolfgang

Might help.

Also, if you are using alternate cloud textures you might be trying to get a cloud to display that
is no longer supported by your installation.
Typically causes ctd at 77% on loading screen progress bar.
