Getting this error every time I launch Mudfish. Doesn’t seem to do much, though it seems to take longer to start now. What does it mean?
Are you running the anti-virus or anti-malware programs? If not please check whether there’s a virus or malware on your system.
Normally this issue happens if another process holds a file reference to files which used by mudfish. Sometimes virus / malware could hold this file or anti-virus or anti-malware programs could cause this too.
Will check for malware, thank you. Otherwise will reinstall mudfish.
Was a malware issue, problem solved. TYVM!
Cool! 
I hope now everything goes well with mudfish. Please let me know if there are any other problems.
