Problem when import..

[Tin . it]

Hello guys,

first, i'm a newbie about CVS and i work under Macintosh and i use a client maccvsX; easy and potent for my scope. Well generally i import and checkout project without problem inside my SandBox.  But today the process of checkout fails when i'll modify a project of PhpNuke.

The process stop the parsing always in the same point, on a empty folder with a simple file 'index.html'. Thi's the error message: 

<x-tad-smaller>cvs server: Updating gsoft_cvs/web_site_gsoft/images/reviews
</x-tad-smaller><x-tad-smaller>U gsoft_cvs/web_site_gsoft/images/reviews/index.html
</x-tad-smaller><x-tad-smaller>cvsgui [checkout aborted]: Internal error: cvs_hqx.cpp, 635: Unknown error: -39
</x-tad-smaller><x-tad-smaller>
*****CVS exited normally with code 1*****

</x-tad-smaller>Please if you can, does anyone here can help me as to resolve my problem??
TIA
