API session expiry?

Hi, thanks for the reply!

I found that my program terminated with the following error:

---

Traceback (most recent call last):

The code is basically as I posted it in the first post (with the addition of some Pygame code to capture from the camera). The only Dropbox functions I use are:

- dropbox.Dropbox()

[once, at the beginning of the program, using my previously generated access token]

- files_search()

[In my main loop (structure visible in first post), I search the app's dropbox folder for files with different names, and then extract the numbers from these filenames to tell the program what to do. This function appears to have produced the above error. Also, I manually edit the filenames via dropbox to instruct the program to take a picture, wait a certain time between loop iterations, or to exit the loop. Perhaps it's my manual intervention interfering with the files_search() function that caused something strange to happen?]

- files_move() [I use this to rename files from their current filename to a new filename which contains a specified numeric value. For example, if the program finds a file called 'imagerequest=1', it will use the files_move() function to rename it to 'imagerequest=0']

...and that's pretty much it! I don't have any exception handling in the program yet, which is why it stopped responding to my dropbox commands when it ran into this issue. Does the error stack provide any guidance?

Thanks a lot for the help!
