I already checked the task manager and there is no second copy of Storyline open. I was not trying to copy the file to anything - the program froze while I was trying to record audio, so I closed it and tried to reopen it and got the error...I have restarted my computer twice now, both warm and cold boot, and am still getting the error...

Greetings everyone.  I just encountered this and thought I'd share another scenario.  Our company has "CrashPlan" running which does background back-ups to the cloud.  When I tried to rename the file, it showed that this file was currently being backed up to the cloud.  I had to force the back-up application to 'sleep' before I could open my file. 

I'm not sure if anyone else has a similar back-up application running, but you might check for that too.

Hi all,

I just had this problem too… I noticed that I had a very long project file name within folders which also had very long names. When I tried to rename it by adding a character I got the “filename too long” error, which gave me the heads-up.

I made the filename a bit shorter, and bingo!

This is getting a bit annoying. I have to apply this workaround every single time I close the project and try to open it again. I realize the last response here is a year old, but this issue keeps popping up in newer threads.

Has this been identified as a bug? Is it being worked on?

Hi, I also encountered this same Error-message. As this is my first project, it was a huge scare. The re-naming worked (thanks for the tip), but surely after more than 2 years of people struggling with this issue, should this not have been addressed (like in fixed)?

I followed your steps - installed the new version. Installed all the updates, but finally, I had to re-named it to enable me to work on it.
