Equalizer doesn't like mp3

Windows XP servicepack 3, just moved from GOldwave 5.25 to 5.52

When I try to apply the equalizer in an mp3, the peak level is about 2500:1 (what would do around +68 dB, but Goldwave doesn't convert), and the window is completely full of the envelope.
After adjustment at a 0dB peak level, there is a 11 kHz sine instead of the sound.

If I process exactly the same sound, but in a wave file, the equalizer works normally.

If I have a wave file, and save it as mp3, I can process the equalizer normally. But if I close and re-open this mp3, the equalizer does'nt work no more.

Since GoldWave decodes/converts everything to 32-bit floating-point PCM whenever you open a file, this is most likely a problem with the MP3 encoder or decoder. Did you download a new copy of LAME when you installed 5.52?

works just fine here. i'm not sure what that could be....i've had some bizarre things happen that were isolated incidents...but never anything like that.

I just reinstalled the LAME 3.98 encod dll, and it still does it. I add that the mp3 files open and save with no problem, it's only the equalizer that doesn't work when the sound has been opened from a mp3, and whatever be how much operations have been made before.

The MP3 may contain data that is causing the floating point processor to get into a bad state. Having the "Ignore floating point errors" boxed checked under Start | All Programs | GoldWave | GoldWave Setup could cause problems with the Equalizer effect.

The problem seems not to occur anymore, but I uninstalled/reinstalled both Goldwave and K-Lite Codec. Only files who get an illustration embedded from iTunes have some trouble, for opening, if I just remove all tags prior to open, it works fine.
