Can't Open .dwg File

I've been sent a .dwg file and i can't seem to open it, it comes up with an error 'drawing file is not valid'.

I've tried opening it in AutoCAD 2008 and 2009, also Microstation V8.

I've contacted the person that sent it, asked them to send it through again and a .dxf version, he's using ArchiCAD to do these drawings if that's any help.

I've tried using both the recovery tools to see if that works, but it says it isn't a proper .dwg or .dxf file.

I've done what some of the other posts have said and opened it up in notepad.

i found this in it: AC1015

no ide what version that means.

Any help would be greatly appreciated.

Cheers,

same problem here dude...i just posted the same exact problem few mins ago...still looking for advices from members...so far i could get is also use recover. and sent back the file to the owner...but keep hopes high...genius members will soon come out...

AC1015 is release 2000. It is possible that 2009 can't open that release. Have you tried running it through Autodesk's conversion program? True Convert available as a free download from their site.

hmm i'll try that out, trying to negotiate getting it now with the IT people, i'll let you know how it goes.

Thanks for your help.
