MS ATC just dumb controllers

Well, ATC was ignoring my requests - no response.

Anyway, I've figured out how to re-establish the IFR flight plan - I think

When IFR cancelled
1. set heading same as GPS course (if following GPS), turn off NAV and turn on HDG - that'll take care of the aircraft until the IFR is re-established
2. make a note of the next but one waypoint you are heading towards
3. select "create IFR plan" from ATC menu options
3. reload the IFR plan that was cancelled by ATC
4. hit okay, but answer NO to move aircraft to starting location
5. go into GPS, select "flight plan" and then use the cursor to select the next waypoint but one that are heading towards - press Menu and press
"activate this leg" - you want to activate the leg after the one you are already flying
6. Now your aircraft should be heading for the next leg in the flight plan - which starts at the waypoint you are already heading towards
7. Reconnect the GPS to the NAV computer
8. Request ATC for IFR clearance

Why would ATC cancel IFR above FL180 when all flights up there are IFR anyway - no VFR? Seems dumb to me.
