Not Enough Memory to Load Sample

[BR]

Hi,
Recently I tried to load a wave sample of 10 MB, I successfully loaded it but when I tried to create Multisamples I got a warning message that says
"Not Enough Memory to Load Sample", "Sample Truncated".

I checked my sample memory info and I see I've used only 416.50 MB over 1.50 GB. So I don't understand why can't I add more samples.
Any help would be appreciated.

See the screen shots of my Pa4X.

Samples longer than 21.845 seconds are truncated

Thanks menara for your reply.
I guess I had this kind of situation longtime ago but I don't remember how I figured it out.
So any suggestion how can I import the wave sample of 10 MB?

Thanks
