Thanks!
Done reinstalling 3.33. Resume seems to work now.

In the previous attempt i tried to install 3.33 over 3.42 in the same
directory. The old version files didn't overwrite the new version files at
all. Therefore when i thought i was using 3.33, i was actually still using
3.42.....

After i manually removed all the files and reinstall 3.33, resume seems to
work now. Thanks for all the replies!
