Anna Wood 13:40 25 Nov 2016 Locked A message comes up relatively frequntly saying: Assertion failed! Program: ... File: .\mongoose.co Line: 3830 Expression: ctx->sqhead > ctx->sqtail With the options: Abort Retry Ignore What does it mean? Is there anything I can do about it? Thanks a lot :) Govan1x 15:24 25 Nov 2016 Maybe Google mongoose.co and see if you have any of those on your computer. looks like there are a few with the same web address. rdave13 17:05 25 Nov 2016 Possibly your security software removed a trojan but left things behind. Run Ccleaner's registry cleaner then reboot. Ccleaner , click the icon to the left of Ccleaner Free text to download and install, unless you already have it.
