[Wine] Steam installation problem

[Kodiax]

Hello,

I'm using steam on wine for a long time now, after an update a couple of weeks ago my Steam.exe displays an error :
"Steam.exe (main exception): Cannot open blob archive file: CMultiFieldBlob(mem-mapped file): Failed to MapViewOfFile"

I'm not using a NTFS partition tu install steam or tu run wine.

So I'm a bit helpless

I hope you guys can help me
