Animate not exporting after exporting another file

[SomethingStudios5CB5]

So I've been working on a big project, but my computer isn't powerful enough to export it all at once. I was planning to export the project 100-150 frames at a time and then edit it together in Premiere, but after exporting the first part, I couldn't export. I clicked on "Export Video/Media" but it didn't do anything. Please help!

copy each alloquot of frames to a new fla and export from there changing their names so it's easy to stitch together in premiere.
