ValueError: could not convert string to float:

[benyanke]

I'm getting the following error.

Anyone else?

Traceback (most recent call last):
  File "./dl.py", line 25, in <module>
    ptime = datetime.utcfromtimestamp(float(content))
ValueError: could not convert string to float:

Looks like yout last.txt file got corrupted. Deleting it would fix the problem.
