Errors while loading wad in Doom Builder.

[ResidentEvilGod]

So I've been working on my first wad for a bit and everything has been fine up until now that I've started to receive a ton of errors when booting it up in Doom Builder. Most of them are in regard to weapons and enemies I have gotten off of Realm667. The errors are as follows:

 

^{SNDINFO warning in "US.wad\SNDINFO:8682", line 2. Ambient sound 1 is double-defined as "WIND" and "WIND".

Any help fixing this is greatly appreciated!

Have you written the correct names in MAPINFO? Cause to me it looks like you didn't since it cannot find those actors.

The same goes for the "chaingun", everything's case sensitive, you just need to correct them for these errors.

In the SNDINFO instead it looks like you defined the FIRE and COMPUTER sound twice or used them twice fro different things.

For the rest (and if the solutions are not what I said), I guess I'd need to take a look to these files
