      Hi, I work exclusively in version 3.2 and wanted to share a new model I’m working on with a friend up in AK. He was unable to open the file (he’s likely using the the latest pro version). I just downloaded the the free version of 4.46 and had the same results: [This Is Not a Valid DELTHship File]&[Invalid Floating Point Operations]. Does anybody know what is going on? Is it possible that the problem is with my old 3.2 program? It seem to be working properly in every other function. Anything I can do to share files? I don’t remember having this problem in the past. Could it have anything to do the newly released version 4.46? Is there no back compatibility? Cheers, Dave

      I’ll add a file in case others what to try for similar result.

      It seems the file has been created with a version of Free!ship later than 2.6.
      I’ve checked, but the file format is not compatible with any of Delftship’s formats.
      So either you have saved your file with a later version of Free!ship, or the file is corrupted.

      I’m thinking the file is corrupt. I just wonder why? Maybe my version of 3.2 is broken (Version 3.2+ is what information is given on the title page as the program loads). So… I wonder if my program will also wreck any DXF file I try to save. Do you have any way of testing a DXF? Just in case you do, I’ll attach one for you.

      So strange that I never had this problem in the past. I recall having to reload WINDOWS not too long ago. Maybe when I put Free!Ship back on my HD I used an executable file that went bad in the interim time period. That is a real shame if that’s the case.

      Hmmm… DXF files don’t seem to be an allowed file format in the forum. I couldn’t upload it as an attachment. Marven, if you or anyone else following the thread has a way to test a DXF file I’d love to know if they are any good. I’ll list my email; anybody interested in helping please give a shout. We should be able to email it back and forth I would think. Thanx, Dave
