Hello there, virusys.

I haven't heard from you in a while. Allow me to lend a hand with using the Intuit FCS Service.

If you continue to experience any problem with the QuickBooks components, you can go ahead and perform Clean Install/Uninstall. For the detailed steps on how you can perform the process, I'm adding the article I suggest:

Please be sure to let me know if you have additional questions or concerns. I'll be around for you.
