Hey Fran,
It's great to hear that the training went well, remember to take advantage of our Webinars when you need a little extra help.
I have checked with our team and we had nothing going on last night as far as updates or any kind of maintenance. One thing to check is that time that is set for doing a "Full Sync", if this was running it may have slowed you down a bit but only for a moment if at all.
Do you have virus software? Sometimes scans can be setup to run at specific times. confirm nothing else is scheduled to run at that time.
Let me know if it's not anything I mentioned.
