AS2 - How to fix the error "Parse Unexpected" from FlashDevelop

Question

I'm trying to compile my classes in ActionScript2 from my project but I can not always get it when I click on the Test Project option it appears this error :

Running C: \ Program Files (x86) \ FlashDevelop \ Tools \ fdbuild \ fdbuild.exe "C : \ Users \ 1 \ Documents \ 1729 \ 1729.as2proj "-ipc a5248614-0afe-4b9a-87dc-1b2a271bec6c -version" 1.14 "-compiler" C: \ Program Files (x86) \ FlashDevelop \ Tools \ mtasc "-notrace -library "C: \ Program Files (x86) \ FlashDevelop \ Library" -target "" Building 1729 Src / MainMovie.as: 4: characters 0-11:

Build halted with errors (mtasc). Done (1)

How do I fix this? It happens in all my projects and classes any help? thanks
