I have a rather large project that I have been able to create evolving versions of by just copying the entire workspace folder. I have accumulated several versions over time this way. Now that I'm using creator 2.1 I'm getting the fitter error "Entry point was not found" whenever I try to build. There is no location for the error so I don't know where it's coming from. I've also tried "save project as" with the same result. Did something change in 2.1 that makes it difficult to copy existing projects? I'm still able to build the origninal project with no problem. Only the copy will not build.

Without having a solution for your immediate problem - why not using a real version control system? Just install git or subversion, and off you go. No more copying stuff around, and no changes will get lost (and you even get a nice diff for each one...).

There is the function "Create Workspace Bundle" which ballows to generate a (compressed) archieve of your project. My experiences show that these archieves can be expanded anywhere and work as expected.

I presume you did a "Clean and Build Project" already.

Today it's building without errors. No changes were made to the project. I guess just chalk it up to quirky things that happen as software gets more and more complicated.
