if used inside stackframe procedure cahnging EBP (mov ebp,eax) may be problem, try to use ECX or whatever.

Code:

struc sx 
{ 
.cBytes dd ? 
.fFixedDisk dd ? 
.nErrCode dd ? 
.Reserved1 dd ? 
.Reserved2 dd ? 
.szPathName rb 128 
} 
OFSTRUCT sx

should be

Code:

struc OFSTRUCT
{ 
.cBytes dd ? 
.fFixedDisk dd ? 
.nErrCode dd ? 
.Reserved1 dd ? 
.Reserved2 dd ? 
.szPathName rb 128 
} 
sx OFSTRUCT

change

Code:

invoke OpenFile,file,OFSTRUCT,ebx

Code:

invoke OpenFile,file,sx,ebx

change spc(0) to just spc.

and file is a reserved keyword in fasm. use other name. also it's better to put any reserved (rb, rd, etc) at the end of source.
