PSP X7 will not start after removing X8 trial

[Zantara]

I downloaded the trial version of PSP X8.
As I am not impressed with this new version, I deleted the trialversion with the cleanup-tool that can be found through this forum.

However, now X7 32-bit, doesn't want to start up at all.

This is what I have done, so far:
* Removed trial version of standard X8 with cleanup tool
* Restarted computer after removal

Does anyone recognise this and is there anything I can do, apart from re-installing X7?

UPDATE:
I rightclicked on the X7 icon on my taksbar en selected one of the recent files I worked with in X7.
Opened without problems and X7 seems to work fine now.
Must have been one of these glitches that happens from time to time.
Hope it stays ok now.
