I re-installed TOPAZ and now it loads the rates each time I log into TOPAZ.
If TOPAZ cannot write the required changes, it will attempt again the next time you log into TOPAZ. You need to check your access rights. The Windows login must have full control over the Datatex folder and sub folders, aswell as rights to delete from the registry.
Once the access has been set. Remove the read-only for the Datatex and sub folders and APPLY. If you have the required access it will update this setting.
Now log into TOPAZ again, it must then update rates successfully. If not then your access is still incorrect.
