[Wine] dll errors on program dlls--works on same distro, machine

[jhthayer]

run Phierha (Pixia), graphics editing program, on Ubuntu, Kubuntu, have running on one installation (on same machine) for quite some time; new installation ran it well for a month and suddenly started erroring on dlls that are part of the program package;  tried reinstalling, no go.  Registry looks same as for the other installation; in particular, all the dlls that are erroring are all registered, in the same way and with the correct path.  

Any ideas, anyone?  Thanks for any help.
