what is this error?

[sonatine]

hi everybody,
today when i opened zennoposter on my personal computer i got this error:

when i press Ignore or any other options nothing happens and after a few second i'll see this window again.
i don't know how did it happen and what shall i do?
i have this version : 5.10.5.1 and it's first time after a few years i see such error.

Looks like something with resources...Maybe you got lack of computer resources

i didn't have this problem before, even when pressure on resources were high!
i'll try to restart my pc and re-open ZP.
i'll let you know. i hope this was a temporary error because i need this magic software more than before and i don't have time to re-install that.

Try to update Net.framework in your system to avoid this issue in future
