pyAesCrypt issues

[SaintFromMsk]

Hi everyone.

Made a small script for batch file encoding:

import pyAesCrypt
import glob
import os
bufferSize = 512 * 1024
curDir = os.getcwd()
password1 = input('\n> pwd: ')

print('\n> Onwards...\n\n')
for x in glob.glob('test\\**\*', recursive=True):
	fullpath = os.path.join(curDir, x)
	fullnewf = os.path.join(curDir, x + '.aes')
	if os.path.isfile(fullpath):
		print('>>> Original: \t' + fullpath + '')
		print('>>> Encrypted, as: \t' + fullnewf + '\n')
		pyAesCrypt.encryptFile(fullpath, fullnewf, password1, bufferSize)
		os.remove(fullpath)

But every time i launch it, i get this:

Error:
Traceback (most recent call last):
  File "encryptFile.py", line 15, in <module>
    pyAesCrypt.encryptFile(fullpath, fullnewf, password1, bufferSize)

ValueError: Invalid IV size (64) for CBC.

My guess is that it is induced by differences in encoding (length does not match block size), but i have no idea how to fix it.
Any advice? (If it'll be a couple of strings of code, and advice where to put it, i'll be very grateful. I'm kinda new to cryptography, worked only on DSM/NLP libraries integration).
Thanks, in advance!

Fixed by doing a clean install of all corresponding libraries.
