Macrium Reflect error BEX64 (Win error?) on MR startup

After installing win7 64bit home premium I cannot rum Macrium Reflect (free).
On startup of MR I get this msg:

Searching MR forum the only lead I got was Win VSS. (MR won't let free users register for forums)
VSS is autostart and running. I re-registered VSS componentsand that didn't work.
Any ideas or help?
Thanks,
